The new ramen place on 10th street (b/w 1st and 2nd) is really good. It's tiny, with about 10 seats along a counter behind which the ramen gets made. Menu's pretty highly concentrated, too. Soy, salt, and miso flavored ramen, gyoza, and chahan, which is a really delicious fried rice dish with egg, scallion, shrimp, scallions. The noodles are a lot better than average, with just the right amount of give to them. Same owner is responsible for Shabu-Tatsu (next door), Sobaya, and Decibel. The New York Post review gives a sense for the place, although some of the details aren't true any longer.
Anyway, I wanted to mention it because they charge $6.50 for a bowl of soup, don't sell alcohol, and don't seem to have much turnover. I fear they may not be long for this world with that kind of dollar volume.
