I'll do a quick review on all of these, as I've been to each of them.
El Campesino - the best mexican chain in pittsburgh. It's about the same as Chevy's. Way overrated.
Patron - about the same as El Campesino, but their drinks are better.
Cocina Mendoza - is in Castle Shannon, not pittsburgh. Thats like saying Sacramento is in the bay.
Rey Azteca - is in Penn hills. See above.
Cozumel - This place is a couple blocks from my house, and we've only been there once. It was fucking nasty.
Franklin Inn Mexican Restaurant - I've actually never heard of this place.
Jose and Tony's - is in Mt. Lebanon, not pittsburgh.
Hungry Jose's Sports bar - not even in the same county as pittsburgh.
