we have some friends in their mid-twenties coming to visit tonight from chicago. they want to experiance the byo tradition they've heard so much about. however, to make matters slightly difficult - the prices have to be cheap (entrees no more than $20, perferably $15)and we need to be able to get a reservation for sometime after 7pm. la viola seems like it might be a good choice as does branzino - but i'm worried that they might feel a little stuffy for our friends - i'd love to take them to a place where they would see lots of people their own age(ish). apamate seemed appealing, but the menu isn't good for one of the pickier eaters in the group.
any help would be great!
