You may have to compete with a couple of inebriated güeros for your 3 a.m. weekday burrito fix, but beggars can't be choosers. Beyond the tempting 24-hour service, when it comes down to it, Nico's dishes out the best cheap Mexican around. Go with the classic carne asada burrito, smeared in complimentary guacamole (you'd have to pay the price of half a Nico's burrito to get that guac as a side at Chipotle). Or wait until the morning after to have your regular eggs and bacon breakfast wrapped in a tortilla and doused in salsa.
