Short answer: plan 4 to 6 canapés per guest if they precede dinner, and 10 to 12 if the canapés replace dinner. On the service side, the working ratios are one server per 10-12 guests for plated meals, one per 20-25 for a buffet, and one bartender per 50-75 guests. For drinks, budget two servings per guest in the first hour and one per hour after that; a 750 ml bottle of wine pours six 125 ml glasses. The number that quietly wrecks the budget is a different one. A WWF study cited in the food waste guide produced by Turkey's Ministry of Agriculture and Forestry with Metro Türkiye and the FAO found that at an 800-guest event the kitchen prepared 900 grams of food per person while the average person eats 450 grams per meal, roughly 360 kilos of surplus for a single event. Below: canapé and drink maths, staffing ratios, the licence side of serving alcohol, how long hot food can sit, where allergen disclosure becomes a legal duty, and what to put in writing in the quote.
How many canapés per person?
There is no single number, because it depends on what the canapés are doing in the run of show. Catering guides converge on this: 4 to 6 pieces per guest for a 45 to 60 minute drinks reception before dinner, and 10 to 12 pieces if the canapés are the meal. In the second case, make 2 to 4 of those pieces something substantial served in a bowl, then add 2 or 3 sweet items. For longer receptions the working rule is 5 to 6 pieces per guest in the first hour, plus 2 to 3 for every hour after. A 90 minute reception for 200 guests at 8 pieces each means 1,600 canapés, and split across 8 to 10 varieties that is 160 to 200 of each. One more thing worth knowing about pace: consumption peaks in the first twenty minutes after doors open. Send half the trays in the first pass and hold the rest for fifteen minutes, so late arrivals still get something.
Cocktail, buffet or plated service?
Service style comes before the menu, because it sets the room, the headcount and the schedule at once. A plated three-course dinner needs the most floor space per guest and runs 90 to 120 minutes. If there are speeches or awards, that time sits inside the dinner, not next to it. A buffet runs on fewer staff and creates queues instead. The common planning figure is one buffet line per 100 guests, and a line served from both sides moves at roughly double the speed. A standing cocktail format is the most flexible of the three and works best for the networking segment before a dealer meeting. Here is the mistake we see most often: plates should not be cleared and glasses should not be topped up during an awards segment or a CEO speech. As long as service staff are moving through the room, the room is not watching the stage.
How many servers and bartenders?
The ratios change with service style. Plated service takes one server per 10 to 12 guests, tightening to one per 8 for top tables that need close attention. A buffet runs at one server per 20 to 25 guests, because guests carry their own plates. Tray-passed canapé service works at one server per 25 guests. Behind the bar, plan one bartender per 50 to 75 guests; push toward the top of that range for beer and wine only, and drop to 50 if cocktails are being mixed. In the kitchen, one chef per 50 guests is the common figure for banquet service. For a 300-guest plated gala that adds up to roughly 27 servers, 4 to 6 bartenders, 6 chefs and a banqueting manager over them. That line in a quote looks expensive. The alternative is service stretched over forty minutes and a main course arriving cold at the last table.
Drinks maths: how many glasses, how many bottles?
Work it in two steps. First, servings: the common planning rule is two drinks per guest in the first hour and one per hour after that. For 200 guests over three hours, that is 800 servings. Second, bottles: a 750 ml bottle pours six glasses at 125 ml, or five at 150 ml. If 60 per cent of those 800 servings are wine, you need 480 glasses, which is 80 bottles. Do not treat the non-alcoholic side as a rounding error. A high share of guests at Turkish corporate events do not drink alcohol, so plan at least a third of the total as alcohol-free and make it visibly equivalent: lemonade, a traditional şerbet, a mocktail in proper glassware. A guest holding a plastic cup of cola is not part of the toast. Water and ice count too: half a litre of water per guest indoors and double that outdoors in summer, plus half a kilo of ice per guest indoors and a kilo outdoors.
Serving alcohol: does the venue's licence cover you?
In Turkey this one has a clear answer. The regulation on the sale and service of tobacco products and alcoholic beverages requires an open alcoholic beverage sales licence, açık alkollü içki satış belgesi, for any sale or service where the retail packaging is opened. Article 10 puts it plainly: open alcoholic drinks may not be consumed or served at retail premises that do not hold that licence. The seventh paragraph of the same article draws the boundary. Alcohol may be served open only at places the Authority has licensed for it, and the areas the licensing authority has approved for the business count as inside the facility's limits. In practice: a hotel's licence does not cover a marquee in the car park across the street unless that area appears on the venue's permit. Plan an alcohol-served opening in an unlicensed factory yard and you have a problem before you start. There is one route around it. For temporary events in buildings registered as immovable cultural heritage, a registration letter from the Ministry of Culture and Tourism plus an event permit from the civil authority can support an application to the Authority for temporary open service permission, and the distance requirement in Law No. 4250 does not apply. Two more lines to remember. Sale and service to anyone under eighteen is prohibited, which is decisive at graduation events. And the 22:00 to 06:00 ban in the regulation applies to retail sales, not to open service at a licensed venue.
How long can hot food sit?
The riskiest part of catering is not the kitchen, it is the distance between the kitchen and the room. Turkey's Food Hygiene Regulation (Official Gazette, 17 December 2011, no. 28145) requires in Article 18 that raw materials and products capable of supporting pathogen growth are not held at temperatures that create a health risk, and that the cold chain is not broken. The same article allows limited periods at ambient temperature for preparation, transport, display and food service, with one condition attached: no risk to health. On site that translates into four questions. Where is the food cooked, how many minutes does it take to reach the room, are there hot-holding units, and how long will the buffet stay open. There is a record-keeping duty as well. Article 40 of the Regulation on Official Controls of Food and Feed obliges businesses producing food for mass consumption on site, and meal factories, to keep a sample of every dish in each batch for seventy-two hours. Staff carry a certificate too: the Hygiene Training Regulation (Official Gazette, 5 July 2013, no. 28698) bars employing anyone without one and makes the owner primarily responsible. For scale, one figure is enough. The World Health Organization's food safety fact sheet, updated 4 June 2026, estimates that 866 million people worldwide, almost one in nine, fall ill from contaminated food, and 1.52 million die every year.
Where does allergen disclosure become mandatory?
That small card in front of the dish on the buffet is not a courtesy detail. The Turkish Food Codex Regulation on Food Labelling and Consumer Information (Official Gazette, 26 January 2017, no. 29960 repeated) requires, in the fifth paragraph of Article 15, that for non-prepacked food served to the final consumer at mass catering premises, the name of the food and the allergens and intolerance-causing substances listed in Annex 1 are provided to the consumer, easy to see and clearly legible, through menus, boards, leaflets or similar. Getting the menu from the caterer is not enough; it has to be visible in the room. Do not guess special menu counts either: ask separately on the registration form about vegetarian, vegan, gluten-free, lactose-free and allergies. Two failures show up repeatedly. Special plates get made in the kitchen and then lost in service, and the fix is a covered plate matched to a table number. And gluten-free options get set on the same buffet line with the same tongs. If a separate line is not possible, send those menus to the table plated.
How many portions should be prepared? Overage and what to put in the quote
The guaranteed headcount is the most expensive line in the contract, and it usually inflates upward. The guide on fighting food waste in hotels, restaurants and other mass catering venues, produced by Turkey's Ministry of Agriculture and Forestry with Metro Türkiye and the FAO, traces the inflation step by step. The client gives a figure of 2,500, the planner reads it as though every guest were an adult male who eats everything, the chef adds an average 3 per cent overage just in case, and the banqueting manager puts out still more so the buffet looks generous. For the wider scale, the UN Environment Programme's Food Waste Index Report 2024 recorded 1.05 billion tonnes of food wasted worldwide in 2022, with 28 per cent of it, some 290 million tonnes, coming from food service. Eight lines to put in writing in the quote: how many days ahead the guaranteed headcount is confirmed and what percentage of overage sits on top; pieces per guest and number of varieties for canapé service; the breakdown of the service team; where the food is cooked and how it reaches the room; how long the buffet stays open and how food is held hot; the number of special menus and how allergens are disclosed; if alcohol is served, the venue's open alcohol licence and whether the event area appears on its permit; and what happens to the surplus. Tales Event is based in Istanbul and runs stage, sound, lighting and LED screen setups for dealer meetings, launches, openings, gala nights and year-end parties across Turkey with a single crew, sharing one run-of-show sheet with the caterer and the venue so service breaks sit inside the programme.
