Chipotle = Moe's = Qdoba = Panchero's = Freebird = Baja Fresh = Uno Mas = <Chain Burrito Place Name Here>
I swear "burrito place" has become a fast-food genre like "burger place" or "chicken place." Anyway, I've had all of the above, and they're basically the same, with regional or personal taste differences. For instance, I love love love Moe's in Florida, where the simmered pork has a great Cuban flavor...but it's only okay anywhere else.
Going wayyy back to the original post --
Uno Mas in SJC Terminal B is pretty good
PHL has "Burrito Elito" and "Cerrito Burrito", but I haven't tried either.
(Ahem) Sorry, carry on...
