Sometimes putting your money where your mouth is...doesn't taste very good. But not all the time. Sure, multimillionaire Scott Ginsburg has used his considerable shekels to assemble a world-class wine list (1981 Chateau Haut-Brion is served by the glass in the bar) and a stunning array of knickknacks. (They include an exploding dish chandelier by lighting designer Ingo Mauer and a bullet-proof glass case cradling a collection of Dale Chihuly glass sculptures.) But if great bottles and swell gimcracks made great restaurants, Woolworth's lunch counter would not have faded away. You gotta have tasty hors d'oeuvres to go with all that eye candy. Or at least tasty liver sans onions (which Voltaire does, only they call it foie gras). There are those rare moments while dining when you slip a forkful of food into your mouth and time stops, or least your Hyundai payments do (Voltaire isn't cheap). This is what eating at Voltaire was like on two occasions months ago. The food was perfectly prepared, the sauces well orchestrated, and the plates brilliantly assembled. But then the restaurant was afflicted with serious stumbles, most notably with service. Missteps spread to the cuisine when Executive Chef George Papadopoulos diverted his focus from the kitchen to grease the gears grinding in the front of the house. All those shortcomings have been smoothed over, however, and Voltaire is once again as good as it was. Now if we could only find some money to put this tasty cuisine in our mouth.
