So I need some help.
I'm trying to throw a special 30th birthday party for one of my friends but there are... issues.

She's said she'd like to do something for dinner, somewhat nice-ish. She suggested the Melting Pot.
The only catch being, she doesn't have a ton of money to drop.
Basically, no money to drop. She has a guest list of about 20 people.
She wants to dress up a little bit, maybe have a private room but not have to pay for said room, spend about -or less than- twenty dollars per person,
and let everyone pay for themselves.
