The first restaurant to open in the eye-catching Oakbrook Promenade complex, Kona Grill offers an exotic twist on American cuisine, with influences from throughout the Pacific. The decor rides on massive blue aquariums, towering stone walls and lantern-like lighting fixtures, while an indoor/outdoor patio boasts fireplaces in the winter and open windows during the warmer months. Drool-worthy appetizers include the Maui onion rings with pineapple chipotle sauce, pan-seared chicken potstickers and avocado egg rolls. Meaty main courses vary from lemongrass-crusted halibut with coconut-curry sauce and white-cheddar mashed potatoes to sweet-chili glazed chicken with baby bok choy. There's also a few pizza and pad thai options, including a shiitake goat-cheese pizza with asparagus and tomatoes. Time your visit to line up with the myriad happy hour deals offered here: A weeknight reverse happy hour from 10 p.m. to midnight (and 11 p.m. to 1 a.m. on weekends) boasts drink specials and half-price pizzas, sushi rolls and appetizers; the same deal is available Saturdays 1-5 p.m. A traditional happy hour (3-7 p.m. Monday through Friday) stands as well.
