We've yet to see anyone actually keel over from or for the juices. They make very good sandwiches, handy to grab on the run. Salads, fresh cookies, they also have good juices, frosties and smoothies. On the ocean side of Hwy 56 at 4-1586 in north Kapa'a shortly before you leave town. Breakfast is very popular and your best bet here.
Lunch is kalua pig, tripe stew, lau lau, pork chops, etc.
Service is totally dependent on who your waitress is. It's very loud inside and crowded, but this isn't a bad choice if price is important. At 4201 Rice Street, Lihu'e. Open at 5 a.m. Moderately priced and marginally edible food, cheap beer.
