I did not mention this before. Space. I know you have to get $$ per square
foot to make a profit, but be reasonable. Make the tables large enough to
hold what a typical diner needs for a meal. Dishes, break basket, wine
bottle, etc. Make the seat comfortable enough. Make the space between
tables wide enough that I can walk to the restroom without hitting the backs
of other's chairs. Waiters don't have to hold a tray above my head while
unloading.
