Authentic, attractive, and friendly. Nah, we're not talking about your dream date; we're talking about the Beachclub Bistro, a casually upscale neighborhood joint, where the gourmet pizzas, seafood, and Italian specialties rock; the wine list rumbles; and our taste buds like to boogie all night long. About that wine list: Among the scores of bargain-priced boutique wines, guests will find a whopping six dozen or so choices by the half-bottle, just right for parties of one or two, as well as for those who would like to match a red wine to their first-course pizza, say, and a white to their second-course fish. And who knows? After working your way through all that wine, your actual date may not seem like such a nightmare after all.
