Hawaii is well known for its surfable waves, flowery leis, and overzealous use of vowels. Pronounce your love of Hawaiian culture with today's Groupon: for $4, you get $8 worth of kava and Hawaiian fare at Bula Kava House.

Judd Rench's Bula Kava House transports diners to the calming South Pacific with a menu of exotic kava and Hawaiian cuisine. Kava, an ancient beverage originating from Oceania, is concocted by mixing water with a ground root similar to the black-pepper plant and straining out the liquid, producing calming effects on the imbiber. Slurp down a lulling libation such as the powerful Hawaiian Isa, which emanates a mild gingery flavor ($4), or the Melo Melo from Vanuatu, a sweet serum so relaxing it could get a grizzly bear to hibernate in a crowded hotel lobby ($3.50). Pair a stress-subduer with a Hawaiian nosh such as the Pele sandwich with pan roasted turkey, Tillamook cheddar, and avocado surfing atop a ciabatta bun ($7). Or, sample the Chocolate Haupia pie, which couples sacchariferous dark chocolate and coconut custard with a nutty, macadamia-shortbread crust ($5).

Adorned with masks from Papua New Guinea, vintage Pacific Ocean maps, and reclaimed tropical-wood furnishings, the relaxing South Pacific cafe tempts patrons to stay late. While basking in the soothing atmosphere, eaters can take advantage of the free WiFi or practice their mannequin impressions.
