A great bowl is hard to find in the Bay Area. For those who don't know, m.n.m is thin Korean buckwheat noodles in cold beef broth, topped with sliced hard boiled egg and varying quantities of Asian pear slices, beef brisket shreds, and pickled cucumber and/or radish. You add your own vinegar and mustard at the table. This dish hits the spot in the summer.
I've been disappointed in what's been offered in SF. However, I liked it at Seoul Gom Tang in Santa Clara, on El Camino and Alpine (in a strip mall w/ a restaurant called Vesuvio). The sign is in Korean and the restaurant is in the inner corner. I'll try out more places in the San Jose area as resources permit. If you have friends who know how to make it confidently, most likely it will be just as good or better than what's in restaurants. And if I'm missing important m.n.m info, I'll be happy to know what that is.
