I just ate at "Radish" on the corner of 19th and Lexington in San Francisco on Saturday. This place is a small hole in the wall with a line out the door that never stopped while we were there. The service was excellent and the food was fantastic,I had the Croque Madame which is ham and gruyere on grilled sourdough, topped with a sunny-side up egg and Bechamel; served with crispy hash. It was close to perfection, Make sure to get the bottomless mimosa if you venture their way. Delish.
