Sushi delicious, rice nicely cooked as it should be. My only issue is the olace is small so eat in feels cramped and there is bit of smell from the kitchen. Food great, atmosphere not

Lovely place with amazing food and drinks.
I got the Tatsuta - Age. It was full of flavour and the portion was perfect. I just wished it was crispier, as mentioned on the menu.
Recommended overall.

Like an addict, I don't know how I'd survive without my biweekly hit of their spicy kimchi beef ramen. Class! But keep the windows open. 10/10.

I had such a wonderful dining experience here. The food was absolutely delicious and presented beautifully.
I was particularly impressed by the salmon sashimi, which was served on a stunning, unique blue-toned plate. Everything tasted incredibly fresh, and the ramen was the perfect comfort food for a chilly day. I will definitely be back soon.

Delicious food and lovely restaurant, probably my favourite place to eat in Leixlip. Good vegetarian options too which I appreciate

Update:
Koshiba called and apologized- We really appreciated the personal attention.
Normally we love the food but recently Koshiba completely ignored the written and verbal request to remove Bell Peppers from a dish - my husband has a serious allergy. So he was sick after eating. So sorry to see Koshiba slipping in this way.
