Here is my Sushi One review. I would avoid it. The best deal for Sushi you can get in the K-Town area is Noshi Sushi, which is a dependable neighborhood joint but nothing special. I would have suggested Shibucho, but unfortunately it is also closed on Mondays. Sushi Go 55, in downtown (15-20 minute drive, more with traffic, hopefully not a worry on Memorial Day), is open on Mondays for lunch and have some decent lunch specials, though you’ll want to double check that they’re open on memorial day specifically.
