I honestly can't say that I'm a burrito connoisseur, but these tasted fine to me. I've had a lot of Chipotle in my life, and these are at least equivalent in quality, though they're pricier.
They have three sizes - the 'medium' was more than enough for me. I wanted to try the tilapia, but it requires a 5-10 minute wait, which is a dealbreaker during a lunch hour. Not too hard to find seats; despite the crazily long lines, few people eat in.
If it's possible, come after 12:30, and the place will be completely empty - you won't have to wait as long in line, and your burrito will be put together with a bit more attention.
