Ever debated about the best burrito in SF? This is your chance to find out. Visit four of the top SF taquerias with your guides Matt and Lael and sample multiple burritos at each stop (sliced into bites so everyone gets to try and no one gets too full too fast). Have a few beers. Walk through the Mission between stops enjoying the weather and the company. We'll vote on the best at the end of the 'crawl'.
