Local places to eat

Hey everyone! A couple of friends and I are coming to Prague tomorrow and are staying pretty central in the old town. Was just wondering if anyone had any recommendations for places to eat/drink that are affordable, local and not too touristy?

In terms of food, we’d love to try local food but we’re open to anything good, as long as it’s not too expensive. In terms of places to drink, ideally we’d like somewhere gay friendly but we’re not interested in the clubs/cruising scene I’ve heard Prague has.

Thanks everyone!
