Rai Rai Ramen, which opened only last April at 915 Race St. in Chinatown, bowed out a few weeks ago.
But if I may shoyu the new occupant:
Nine soups include the familar miso, tonkatsu, and shoyu. Seafood ramen ($11.95), for example, was a bowl full of shrimp, squid, crab sticks and mussels.
Appetizers include dumplings (shumai and gyoza), takoyaki, pork bun, and chicken katsu. You might get the mochiko chicken ($7.95) just for the presentation; the fried strips of dark-meat chicken are served with a bowl of a light-colored mayo-based sauce and a plum-based sauce set up in a yin-yang pattern.
Also cool is the selection of Japanese soda, including ramune (aka marble soda).
