There are none in SF as of right now. I heard there is going to be one some day, not in the near future though.
But there’s one called Asian Grill in Oakland, CA ( quite large Mongolian population in Oakland, Alameda and SF): here is the link to its yelp: Asian Grill. Since there seems to be only one lady working as a cashier, waitress and the cook, so this place is inefficient in some ways, food is delicious nonetheless. I haven’t been there recently though.
I heard there is another one in Sacramento, CA, but not sure if it’s still there. I will ask around and update, since I want to go eat there too.
