I've read a few things, like:
You need tables and chairs.
You need regular floor (not dance floor) near counters.
Counters can't be blocked (though this is pretty obvious)
Is it like Restaurant / Bakery Story where you need 1 chair per table, and the chair must be facing the table? Do chairs and tables need regular flooring, too?
Some more explanation on this would be nice, as well as any tips more experienced players can give. Thanks for reading.
