Everywhere Chris Kronner goes (Slow Club, Serpentine, Bar Tartine) a burger is sure to follow, or at very least a desperate longing for one. A past San Francisco Chronicle Rising Star Chef, he’s found home next door to Bruno’s on Mission Street where the menu includes such oddities as a sweetbread burger, crab burger and ice cream burger. There are fries and onion rings plus a salad or two of course for those pesky vegetarians.
