Jean Paul Sartre opined that "Hell is other people." For those who agree, heaven must be a sushi happy hour so tasty and affordable that you don't mind being surrounded by that most annoying variety of Other People: shoppers at Scottsdale Fashion Square. On weekdays from 3 to 7 p.m., and from 9 to 11 p.m., Kona Grill offers select half-price sushi rolls, $4 sake bombers, and half-price appetizers -- including Sweet Maui Onion Rings, among the best onion rings in the Valley. For folks who hate a crowd, this is a Faustian bargain, since Kona Grill's bar is ever-jammed with sunless-tanner-loving androids discussing condo interest rates. After some tuna wasabi and a few rounds of sake, however, the crowd will seem positively existential.
