Haleiwa Joe's Seafood Grill    Whether you're a vacationer, a surfer or snorkeler, or a resident escorting visitors around the island, Haleiwa Joe's Seafood Grill, overlooking the smallboat harbor on the historic site of what was once the gracious Hale'iwa Hotel, is a nice break on the long drive to and from the North Shore. The food is of the casual, familyfriendly sort — sandwiches, burgers, fried and grilled fish plates with East West touches (poke, tempura crab roll, Thai calamari), and some of the cocktails come in kitschy souvenir glasses. There's a Kane'ohe location, too — set above lush Ha'iku Gardens — but we've always enjoyed the Hale'iwa spot and its beachy character.  66-011 Kamehameha Highway. 637-8005. haleiwajoes.com. 11:30 a.m.-9:30 p.m. Sundays-Thursdays; 11:30 a.m.-10 p.m. Fridays- Saturdays.
