A Kyoto Sushi restaurant has opened relatively recently at 2100 N Snelling Ave in Roseville. It's part of the old HarMar complex. They offer all-you-can-eat sushi from 11 am to 2:30 pm on weekdays for about $16, and from 4:30 to 9:30 on weekdays for about $25. On weekends the prices are a tad steeper. You don't have to do the buffet, of course. The buffet includes sushi, appetizers, teriyaki, teppanyaki, desserts, noodle soup, donburis, etc. for lunch and dinner both.
Sashimi is only included in the dinner buffet.
