TRUFFLE SOB BURGER LOCAL KITCHENS IN SAN BRUNO, CA LOCAL KITCHENS SAN BRUNO, CA Back again to try another Chef Alvin burger special! This time he brings out the truffle! No lie, this burger is damn good! The bun is soft but they grill the inside on both buns, nice and toasty on the interior. The patty is juicy but kinda got a nice crisp on the edges. That truffle sauce is amazing! Get over asap to try it out! #chefalvin #localkitchens #truffleburger #burger #sanbrunoca
