I went there twice, I love it! I wish I could speak better japanese with the gals, they are so nice!
The menu is really appealing, just tell you're a vegan and that will do. Their options are great, the food is perfectly prepared and cooked, the Ramen with Buckwheat noodle tastes delicious, and their menus are really cool! I think it's a bit pricey for the quantity though, if you just have a ramen you might get a bit hungry in the end. Problem is, you just wanna try everything, and it comes in small portions so you eat, eat, eat... and when the moment comes to pay... ouch ;)
Cons: pricey, not very comfy, small portions
