Foursquare Tips

  • Tried the blue crab roll.. AMAZING!! Butterfish was also amazing.. All the fish was fresh and full of flavor. Sat at the bar for Omakase (Chef's choice only) Hiro-san is a delight.
  • Blue Crab Handroll is the best.
  • This is a Traditional Sushi house. Bar is Omakase only. And Dinner is sushi only. If you want to choose your own sushi you must sit at the table. But I suggest you trust Hiro-san. He knows what's good
  • Great little sushi place!
  • Awesome sushi
  • Pretty authentic sushi place, the butter fish nigiri and blue crab hand rolls are outstanding
  • Butter Fish Nigiri is so good. Don't dip it in soy sauce.
  • I've been to sooo many sushi places.. this is the most traditional. Just remeber you are here for the food not the servixe ;-)
  • Good food. Good people but only one sushi chef. Plan lots of time.
