The one problem I've had with cast iron is that newer stuff seems to have a rougher profile than older and therefore slightly stickier.

Holy Frijoles in Hampden is also dead cheap, although it's not authentic Mexican and all the waiters are total hipsters.

There's also good Korean BBQ at Jong Kak on 20th. The neighborhood can be a little sketchy at night, but I've never had trouble. Just don't leave your GPS in the car.
