I did "Loves" a few summers ago. Its a very fun but busy show. The best advice I can give is to keep on top of all the props as much as possible. We had problems like "where did spatula #4 end up after it was thrown across the room?". Its just one of those shows were everything needs to be very detailed or it turns into a cluster f*ck very quickly. We used real soup, and real eggs, but I think that was the only real food we had. Of course, lots of water all over the stage. Make sure you keep a mop/ broom handy during tech.
If you have specific questions, please let me know and I will be happy to help.
Have fun!
oh.. and try to stay out of the splash zone!
