Addicts know that sushi can be an expensive habit, especially in the landlocked Midwest. But $1 sushi specials make it possible to get your raw-fish fix for little more than the cost of fast food. Friends Sushi and Bento Place (1808 West 39th Street, 816-753-6666) shills sashimi and sushi pieces for a buck each between 5 and 9 p.m. Mondays and from 11 a.m. to 3 p.m. Saturdays. Rolls go for $3.99 at the same times. The menu at Friends includes staples such as tuna, plus some more adventurous cuts. The crunchy, spicy salmon roll makes our scalp tingle. Just make sure you get to Friends early and without too many friends in tow. During the sushi sale, this tiny eatery can feel like a sardine can.
