How well do you know the burgers of the Bay Area? Take our Burger Master Quiz to find out. Below we’ve chosen pictures of twelve excellent local burgers found across the Bay Area. Two readers that guess all twelve correctly and send in their answers to the contest line with "Burger Master Quiz" in the subject box will win a burger CSA from 4505 Meats. It'll have 1.5 lbs of fresh, locally sourced, grass-fed, dry-aged beef grind, five hand-made signature sesame seed burger buns and all the fixings: iceberg lettuce, sliced red onion and 4505's secret sauce. If there are more than two perfect submissions, the winners will be chosen randomly from the perfect answer pool after the Friday, April 29 5 p.m. deadline. Answers and winners will be revealed next week.
