We entered by accident, but will come back by design.
The food and the service were both excellent. Our server was the owners' son and he clearly had great respect for both his parents, their work and their restaurant. He gave us excellent menu advice, and was able to help me, the near-vegan to navigate ordering and eating without so much as a splash of fish sauce.
The Ban chan (Korean appetizers of assorted pickled vegetables) were great. When our server noticed that we had eaten one more quickly than the others, he brought us another plate.
I had a vegetatrian Be-bim-bop, with tofu instead of beef and extra vegis instead of egg in a stone bowl (get the stone bowl, it's so worth the extra). Things were fresh, tasty and well seasoned.
While I am not usually a fan of restaurants with only one vegetarian option, this one is so good I predict that I will be back again and again. Heck, I'd go back for the ban chan alone.
