Thanks!
First I want to thank all of you who replied. You've been so helpful!
I agree that the budget is unrealistic and I don't work for free (OK, I did work for free on my first catering because I missed a decimal!). The $800 is just for food. The bride knows I'll be tacking on my costs when we come up with the final figure. I think she will be shell shocked. People don't see behind the scenes where we plan the menu, look for recipes, experiment with new recipes, go shopping, figure out the timeline, find servers, do a tasting dinner, etc. OK, off my soap box.
Chef Andrea and Gina, I may indeed turn this one down, at least at the price the bride has given me. She started with a higher budget so I suspect some got diverted to the honeymoon. However, when I tell her the limitations of an $800 budget she may throw in more money.
I think I will probably suggest a dinner menu rather than just appetizers. The venue is Lake Tahoe, about 3.5 hours from where I live and considering the wear and tear on me and my staff, the dinner is easier. It would definitely be a bring the food, put it out, clean it up and get out deal.
I'll let you know what we finally decide. Again, thanks for all the great ideas.
