You’re a bargain hunter. Those Chloé booties? Sample sale. Your Brazilian-ed mane? A deal.But sacrifice when it comes to eating out? Never.You don’t have to, with the opening of Keiko à Nob Hill today. The restaurant from Keiko Takahashi and Seigo Takei (the Michelin-starred chef of El Paseo pre-TyFlo and her wine connoisseur husband) offers fine dining and a collector’s wine list (5,000 bottles strong) for less than you might expect.Tucked into a residential building, the space is like an intimate Parisian apartment, with a receiving lounge (parfait for sipping champagne) and two dining rooms brimming with European imports.The $88 prix fixe ain’t pocket change, but for Keiko’s cuisine (a lauded fusion of French technique and Japanese flavors) it’s a steal. The menu will change nightly, but expect variations of extravagant farm salad (above), scallop saute with sea urchin, and foie gras, plus a limited-time lunch menu. Or nosh on more casual izakaya-style fare at the bar.Doesn’t every pied-a-terre have one?Keiko à Nob Hill, 1250 Jones Street, at Clay Street (415-829-7141 or keikoanobhill.com).
