Phao in Sag Harbor knows how to turn up the BTUs. It's downtown's spice rack. Try the wok-charred shrimp with a sweet-hot sauce; green-curry chicken; and the shrimp-lemongrass soup. For a more soothing approach: chicken satay, vegetable spring rolls, curry puffs with potato and chicken. Phao is at 29 Main St., Sag Harbor; 631-725-0101.

Thom Thom in Wantagh has has several lives. The current one emphasizes steak and sushi. But the kitchen has kept the sweet-hot-crunchy kung pao calamari, with chiles and peanuts. The coconut shrimp satay with a mango-and-chipotle dip also is good. The sushi pizza and the sushi rolls are dependable. Sample the marinated skirt steak, too. Thom Thom is at 3340 Park Ave., Wantagh; 516-221-8022.

The Curry Club sparks your appetite with chicken or lamb vindaloo; the crimson stew, rogan josh, that's best with lamb; tandoori chicken and tandoori prawns; vegetable samosas and vegetable fritters; and papri chaat, or crisps with chutney and potatoes. Enjoy dal makhni, or black lentils; and chana masala, or chick peas and potatoes. The Curry Club is at 10 Woods Corner Rd., East Setauket; 631-751-4845.
