You'll want to find a place with soft lighting, well-dressed waitstaff, private tables and exquisite food.
It may seem strange, but the way a man acts around his friends, towards waitstaff, or around strangers can be as much a part of flirting as the fabled "line."
Customers come into the restaurant, waitstaff takes care of their orders, the chefs cook the dishes, and money comes in.
If there are more customers than the waitstaff can handle, then they will end up leaving - so you have to maintain a balance of several different factors.
The food is cooked on skewers and transferred to the patron's plate where the waitstaff slice it.
