I really enjoyed this Mexican joint over in Leblon. The food's great and cheap, especially on weekends where they have an all-you-can-eat buffet with a wide variety of goodies.
I didn't run into any other Mexican restaurants around Rio (and trust me, I looked), so I imagine this is the one to go to. You'd better skip breakfast if you plan on spending an afternoon here!
