Late at night, downtown Houston is awash in lights, a nonstop fashion show of men in black and women in too-high heels and drop-dead dresses. For this crowd, only the wildest, most electrifying dining experience will do. And Saba rises to the occasion. The Small Plates menu is a list of stunningly original dishes such as shrimp and pork pot stickers, crawfish cakes with daikon salad, and coriander calamari with smoked tomato aioli. Dinner items include dishes such as herb-crusted tuna, medium rare sushi-grade tuna topped with soy paste, wasabi and sesame seeds on a bed of slick udon noodles and tender wilted greens tossed together in a ginger shallot vinaigrette. Chef Larry Perdido and his staff have figured out how to handle the fusion challenge. They start with a single focus -- seafood -- and then they improvise. They mix. They match. They combine seasonings and sensibilities from various cultures and come up with some very bright ideas of their own.
