Do they pay local bands to play? and about how much could a local musician expect to get?

Not sure, you would have to call to find out... They do allow open mic nights. It's not as busy as some of the other bars so I'd call around for booking gigs

Don't know how much you would get paid. Call the Trolley and ask to speak to Robin.

They do pay entertainment (local, national acts alike), but you would have to contact them directly for specifics. Billie is correct about open mike nights, too.
