Once you're tucked into this comfy little den in South Beach, you'll forget about the riffraff and party buzz outside on the dingy sidewalks of Washington Avenue. The lights are low, the candles are lit, and it's time to order some nan. If you've worked up an appetite paddling on the surf a few blocks away, Guru's cool mango lassi with sweet cardamom and salted cumin is a refreshing way to revive yourself — and your eyes will appreciate a break from the blinding sun. Snag one of the few cushioned wicker chairs for maximum relaxation. Selections, served from 5:30 to 11 p.m., include chicken makhani (Guru's specialty boneless chicken in a creamy tomato sauce, $15.90) and Kashmiri rogan josh (lamb curry with ginger, fennel, and chiles, $17.90). Curried jalapeño crabcakes, chaat wafers, tandoori fish, shrimp korma, lamb vindaloo, and saag paneer are just a few of the choices that round out the menu. Vegetarian? Guru has plenty for you. Vegan? You're covered; just be sure to ask about dairy, etc., in the entrées you're ordering — some dishes include cheese but don't say so on the menu.
