I think pride is contagious in a restaurant. The owner down to the bus boys are hard-working proud people in my favorite places. The problem is that some chefs/owners seem to be unable to swallow some pride when their big idea doesn't work out.

Pride

Flexibility

Humility with confidence

Appearance (I hate slovenly waitstaff:look sharp/work sharp)

I agree with the folks' comments on music. I hate that loud crap. I've got headphones at home. I'm out with friends/family I would like to have some banter with people who came for the same.

Little things. Give me crappy bread and I'm not expecting much from the kitchen. Again pride leads to good appearance and mental sharpness from the workers. Cleanliness, customer enjoyment and the little things are EVERYONE's job.

I don't envy you. I wouldn't know where to start. Just commenting on things I've observed.
