I second Milagros Boutique's community room
It's totally byo food+drink, which is great if you have dietary concerns or just like more control/less cost than a restaurant ... it's a community-meeting type room with toys and painted in vibrant but not dayglo colors. There's a couple of couches, some chairs, a couple of tables ... last time I rented it it was $60/3 hours ... about 16 ft x 40 ft, I'd guess ... bathroom is through a stockroomy type closet, is the only thing you really have to watch the kids about. The nicer bathroom is accessed through the adjacent Boutique itself (french doors connect).
Full disclosure, I know the owners ... but I met them AFTER I fell in love with the space ;).
