Snazzy and Jazzy at Yoshi's

Traditionally, you don't go to an entertainment venue for terrific food. Whether it's a jazz club or a medieval jousting tournament, what's on your plate comes a distant second. Food is offered as a courtesy at some venues to encourage your drinking, and can be used as a sort of bribe: The best seats in the house are reserved for those who make a dinner reservation in advance of the evening's festivities.

When I first visited Yoshi's Jazz Club and Restaurant in the new Fillmore Heritage Center to hear Cuban jazz, that's what I thought we were doing: having dinner and listening to music in the same location. But when you enter the cavernous, soaring place, you're immediately aware that you're in a real dining establishment, not simply a nightclub, and an audaciously conceived restaurant at that. The performance space, as it turns out, is at the back of the building's lobby, with its own entrance.

Entering the restaurant is dramatic. You walk past a sculptural installation of carefully placed rocks and wood, a tiny Zen garden, and a dazzling white-and-steel open kitchen, and into a room that somehow seems both overwhelming and intimate. Some acoustic genius has devised a way to permit conversation at the highly polished wooden tables, despite the impossibly high ceilings and hard surfaces. Everything is in neutral, natural hues. Huge Noguchi-like sculptural paper light fixtures and filmy hangings divide the space. There's a glamorous two-level lounge, lit with glowing purple and blue lights, that wraps itself around the kitchen. It features cozy sofas and chaises as well as small table seating.

Yoshi's has come a long way from its beginnings 35 years ago as a tiny sushi bar in Berkeley. After moving to a larger space on Claremont in Oakland, the owners added live music. Yoshi's next move to Jack London Square at the invitation of the city a decade ago was intended to help revitalize that neighborhood; similar civic intentions are behind the new San Francisco location on a strip of Fillmore once famed for jazz clubs (the sidewalks are indented with plaques bearing the names of long-vanished venues and musicians).

The five of us are seated in a booth near the windows overlooking Fillmore, with a thin metal screen divider that could be pulled back for larger parties. During our meal, the other half of the booth was offered to two couples, who both preferred to be seated at their own tables.

The huge menu is divided into nine sections: zen sai (appetizers), ippin (small plates), agemono (deep-fried), otsukiri and morikomi (sashimi plates), nigiri sushi, maki sushi (aka rolls), robata (food from the charcoal grill that's visible in the front of the kitchen), and kamayaki (from the wood-burning oven tucked away toward the rear), plus a few sides. Yoshi's has hired a star chef, Shotaro "Sho" Kamio, who opened the respected Ozumo in San Francisco in 2001; he is devoted to modern Japanese food using the best seasonal ingredients. Our server tells us that everything on the menu is designed to be shared, and suggests two to three dishes a person.

Our first meal is something of a mixed bag. The largest sashimi assortment of the three offered, called sanban, includes two slices each of nine different varieties (bigeye tuna, bluefin tuna, yellowtail, salmon, sea bream, salmon caviar, crab, prawn, and sea urchin). It's beautifully presented and exquisitely fresh, but difficult to apportion among five people – and at $50, I'd rather sample other dishes than order another round. I'm beguiled by the slightly smoky seasonal organic vegetables roasted in the oven and wrapped in cedar paper, but more unusual dishes miss the mark. The layered "ravioli" of flattened squid mimicking pasta, sea urchin (uni), and shiso pesto seems like a stunt that doesn't showcase either the squid or the urchin, which is similarly lost in the uni "risotto," in which vanilla-scented cauliflower puree is supposed to be the "rice." A pricey chawan mushi containing lobster, foie gras, and more uni is liquid rather than custardy, and its ingredients are again obscured.

The straightforward free-range lamb chops with fresh wasabi and garlic mousse would do credit to any contemporary restaurant, but are again awkward to share, and I've had better versions of the miso-glazed black cod. The zesty geisha roll, with spicy shrimp tempura, snow crab, and tuna, is tasty, crunchy, and quite generous. Even though our server knew we were headed to the club, we've run out of time, and have to skip dessert. We haven't drunk much (one bottle of wine, one carafe of sake), and I'm still slightly hungry. But a choice table has been reserved right on the dancefloor of the two-level club for us, and we settle in for part two of a lovely evening.
