Management at Liquid can’t promise that we won’t have any more 85-degree days after the Third Annual End of Summer Luau, but it’s always a little cooler by the lake. The luau’s festivities include live reggae from Carlos Jones and the PLUS Band and an end-of-season barbecue with chicken, shrimp, and — if you’re in the mood for something lighter or less cooked — Hawaiian food from neighboring sushi bar Fusion. Grass skirts are optional.
