South Shore Grill. Just a couple of minutes out of Waikiki proper near the base of Diamond Head, South Shore Grill is an affordable counter-service spot. It's especially convenient if you need to refuel before or after sightseeing or beach time. The restaurant is also known for its fish tacos, and offers sandwiches (on ciabatta rolls), entrée salads, stuffed burritos, and a plate of ono (wahoo) coated with macadamia-nut pesto and served with a tangy slaw. 3114 Monsarrat Ave., Diamond Head, Honolulu, HI, 96816. 808/734–0229. www.southshoregrillhawaii.com.
