Thus far, after one year, Cancún has my vote for the best burrito in Berkeley. Unfortunately, it’s about a buck or two more expensive than other other places, but in my opinion the selection outweighs the cost. Here you can find mole, nopales, and other burritos that aren’t at the other places near the Berkeley campus. They also have 3-4 different agua frescas available, which is the perfect way to cool off after a hot day in the sun. To top it all off, they have about 12 different salsas to choose from. If you go there for the first time, I recommend trying as many as possible. Most of them are pretty tasty, but watch out for the ones that say they’re spicy!
