Kubo's Japanese Restaurant Chef Kubo was the best sushi man in Houston. Unfortunately, he left town several years ago, but he trained his replacement, chef Hori, very well. The new sushi master is doing an admirable job of filling Kubo's sandals. There's always something interesting on the specials board at Kubo's, and the fish is always the very finest in quality. An even younger chef named Suzuki, who is fresh from Japan, is executing some splendid renditions of traditional sushi preparations. His chirashi, presented in a textured, three-tiered bowl, offers artful compositions of sashimi, radish shoots, seaweed, rice and other elements tucked one beneath the other. Crazy rolls and the like are done by a pair of imaginative Latin American sushi chefs. They also run a special all day Sunday, when every piece of sushi sells for $1.25.
