Reader Susie let me know that Sun Sushi has opened at 3631 State Street, in the former home of Ahi Sushi that closed late last year because the owner moved to Colorado. When I interviewed Sun Sushi co-owner Max Kuo, who used to work at Ichiban on the Mesa, I got the impression that his new restaurant offers serious quality and is run by management and chefs who know what they are doing. I would recommend sushi lovers to give them a try. Sun Sushi has been remodeled and updated since the Ahi Sushi days. They use only fresh fish that is never frozen. On Tuesdays and Thursdays they serve fresh fish that is flown in from Japan as a special item on the menu on those days. Kuo suggest you try their Sushi-6-Steps offerings which is a served on a six wooden steps that form a staircase that emerges from your table, and includes soup and salad. The Salmon 6-Steps ($18.96) include 6 styles of sushi made from 3 types of salmon (Scotty, Atlantic, and Ocean-Trout). The Blue Fin Tuna-6-Steps ($37.95) again offers 6 styles of sushi using exclusively Blue Fin tuna. Call 845-7720.
