I've been craving burritos since I arrived in Buenos Aires two years ago. About two weeks ago I was walking down Lavalle on my way to Puerto Madera and walked by a restaurant called "California Burrito Co." On my way to meet a friend, I couldn't stop in, but I was able to stop-in the other day. I have to say, I had one damn fine burrito. I had their "California Burrito," which comes with your choice of meats, rice, beans, salsas and guacamole, and extras like cheese, lettuce, sour cream, etc. Oh man, deeeeelicious! Sure, I just might be missing burritos so much that my expectations are fairly low, but it felt so good to eat something other than bife de chorizo. I plan on going back next week for a second try, so I'll report back with my finding.Not sure of the exact address, but it's on Lavalle, between San Martin and Reconquista.
