Although you wouldn't expect it from a wine bar, Plonk has one of the best bacon cheeseburgers we've ever tasted. And that's because Plonk is more than just a wine bar: It combines excellent food with expertly chosen wine and beer in a cozy, neighborhood setting. The guanciale burger is the best example of that food. Its buns are toasted in the pizza oven while Swiss cheese melts onto the top bun, and when combined, they sandwich a huge patty that's rampant with beef juices and covered with caramelized onions and "face bacon." The face bacon is that eponymous guanciale that is bacon's fancier and tastier cousin, trimmed from the pig's jowls and cured until delicious.
