What's wrong with a military-themed restaurant?
Everything is at least 5 years old, you use C-4 or MRE heaters to heat everything, and of course, the items on the menu should have creative and fun names, such as:
--Baboon's Ass (corned beef)
--Dreaded Breaded Vent Covers/Elephant Scabs ("meat" Parmesan)
--Cat turds (Beef Cordon Bleu)
and of course, who can forget such classics as:
SOS
Horsecock sandwiches
Bug juice
I'm tellin ya, it can't lose!
