Indian cooking blends sour, spicy, and sweet flavors—a feat otherwise only possible by chugging lemonade after applications of tabasco fluoride. Sample the proper pairing of these fickle flavors with today's Groupon: for $20, you get $40 worth (or $45 worth if redeemed Tuesday through Thursday) of Indian fare at Arusuvai Chettinad in North Brunswick.

Arusuvai Chettinad's spice sages bend the six tastes to their whim while crafting authentic cuisine from across India. The menu melds tandoor, biryani, and thali dishes packed with meats and vegetables. The ennai kathirikai dunks indian eggplant buoys in a bath of Southern Indian–style tamarind-based sauce ($8.95). The mutton sukka varuval ornaments tender cuts of goat meat with tiaras of crushed peppercorns and curry leaves ($12.95). Chefs also trim lamb chops into individual portions before marinating the bone-in meat and grilling them in the volcanic confines of a tandoor oven ($12.95). Children's combo meals let parents introduce kids to the Indian subcontinent without buying a plane ticket or waiting for the Pangaea reunion tour. Decorated with Indian art, the restaurant’s warm, earth-toned walls surround wooden tables and colorfully patterned booths.
