The ones where the company is what matters and the ones who are most interested in there you're going/what you will eat.
For example, it's my friend's birthday, she wants to go out for dinner. Of course I'd love to go. It doesn't really matter where, there'll be something I can eat on the menu and it's all about the company. I might balk if she chose somewhere very expensive, but other than that I'll be there.
Otoh there are a lot of objections to a chain type restaurant, someone who doesn't like Indian food, someone who "can't" eat fish (there are other things on the menu) and one who won't go unless sea bass is on the menu!
