While some argue that a steamy San Francisco burrito is as complex and interesting as a clam chowder sourdough bread bowl, the local foil-wrapped burrito -- packed with rice... and stuff -- has its fans. Many of them, in fact. Probably you. Which is why the superb 2010 Mission Burrito Book, a site devoted to one man's burrito-eating experience, culminated yesterday by naming the top burrito in San Francisco. Papalote came in at #5, Los Coyotes at #4, El Metate at #3, and... well, you'll have to visit 2010 Mission Burrito to find out the top 2 picks. (The entire site, brief and to the point, is worth a look.) [Grub Street]
