The quest for the best burrito in the Bay Area is a daunting one, but also quite fun and filling. I limited the geographic range to San Francisco, Oakland and Berkeley, which leaves out the South Bay. What makes any burrito “the best” is its taste. To be as scientific as possible, I got the same basic burrito at each place – flour tortilla, cheese, rice, pinto beans, grilled chicken, salsa, guacamole and a dab of sour cream. I found that I surprised even myself: with the benefit of side-by-side tasting, my picks for the best were not what I expected before starting.
