Hello Rose,


I didn't understand you message not really clear but here is a try


From my point of view this is how we calculate in Paris

---------100 people--------------------

for Savory items such as chicken ect..calculate as 60% meaning you need to make 60 portions of that chicken, if you are using only chicken breasts you calculate like this : IF you making only chicken for the 100 than you need to make at-least 120 portions

if there's other savories than 60% of each

100 guests - 60%   (60 portions needed)

1 breast = 6 portions

you need to buy 10 breasts + 20% (Extra in case) = 12 chicken Breasts  this is an example

For the ice cream it's about third of cup for each  berries Fruits 30g for each  about 3 kgs

For Fruits display

3 kgs bananas

2 kgs Peaches

2 kgs of strawberries 

2 kgs Apples

big Water melon

5 small melons

5 lbs of Raspberries and blueberries,

6 Pinapples



Hope this help and good luck to you

The head count ( actual number of people attending) is always important in an initial post.

The amount of food per person that is eaten is lower with a party of say, 30, than a party of 250.

I don't know why, it just consistently works out that way. Maybe eating is infectious; bigger parties

just seem to consume more in their path. Like Army Ants.:suprise: 

100 is somewhere in the middle, but it also depends on whether its a served buffet or a self service.

And  though you've cut the chicken to "portion size", that only works if it's being handed out.

Otherwise, main meat portions don't mean a lot in a self service buffet--people take what their

hunger tells them to. So in a  served buffet I'd allow 3 or 4 oz per person, in a self serve more like 6 or 7.

Also---the amount of food used/wasted depends on the length of the line at the buffet---


If the line is long and slow--diners will heap on more food because they would not want to wait in line again for second helpings----


Keep the lines short---
