A whole bunch chefs and restaurants show up with their best burger and vie for votes from the crowd. This year, Katie Lee Joel won with a patty melt. Laren at Gothamist has some pictures to go with her recap and Grub Street offers details on many of the entries. WPIX has a great photo gallery of the event (just click on the funny picture of Rachael laughing and it will open up).
