I adore Rockmeisha! Little place tucked away on Barrow St just east of 7th Ave. in the West Village. It's my favorite Japanese joint, possibly the most underrated, because it serves dishes from the chef's home of Kyushu that you really can't find anywhere else in town. It's a gem. Real downhome Japanese food, comforting. Try to order things you don't see elsewhere in town (Japanese soupy omelettes, fried chicken with tartar sauce, pork with leeks and sprouts in a cast-iron pan), but standards like broiled mackerel, freshly wrapped gyoza, and shrimp dumplings are great, too. I don't ever go there for just sushi. The ramen is fantastic with special noodles flown in from Japan and an authentic, rich tonkotsu broth (especially good for people who want an authentic rich broth that is not quite as thick as Minka's). Those noodles are addictive. Service is super friendly and laid-back, but attentive. Not good for groups of more than 6.
Pros: great, authentic, local Japanese food; very friendly service and ambiance; open late
Cons: no fresh green tea!; cha-shu for the ramen soup was average
