To update, the brach which is now closed down is Sukhumvit branch, now they operate at Songwat road, locates near Mongkoltan temple, behind Lim Hi Lee Kitchen.
The place is small and very simple, but the food is nice.
Various dishes to choose for example different kinds of Sushi, Temaki, Grilled, Stir fried, Deep fried, and Soup.
They do not use 'fake meat' which made from flour in their dishes, but use tofu, konjac, mushrooms, and vegetables.
I love their Sushi, very well mixture containing vegetables, mushroom, tofu, and of course seaweed. :)
