When you enter Sushi Zushi, assuming it's not a jam-packed Saturday night, you'll be greeted with a chorus of shouts in Japanese from the waitstaff and sushi chefs. As startling as it may seem (and many potential diners took great pains to ignore it), "Welcome!" is their message. (Irasshaimase!, if you prefer.) Yes, with exclamation points. And it's typical of the restaurant's enthusiastic attitude. Get used to it. ;The exuberance spills over into other areas as well. Despite a pleasant, minimalist decor featuring melon-toned walls, a laminate floor intended to emulate wide-board pine, and some black-and-white images of the sushi-making art, SZ doesn't come across as understated shibui. You can't sit at a counter to watch sushi masters assemble your order with deft hand and quiet dignity. In the place of deferential waitresses in traditional garb, there are kids in grey polos and black pants. And numerous items on the almost intimidatingly long menu, feature chipotle mayonnaise. Get used to that, too. - Ron Bechtol
