"We tried both normal one and the hot pot one. Must say that the normal one, in our opinion, is a bit better. We felt like the taste of veggie in the hot pot one is too strong. Chashu pork is excellent! Price is okay. Will give it 4 stars for now"

"Delicious japanese ramen at the center of Siam Center. Space is quite small so cannot hold a lot of customers. Ramen is soft and delicious. Varieties of ramen menu is also good and enough to choose. Staff is also support to explain each menu."

"We had seen good reviews for this one and it did not disappoint! We were 9 of us and they accommodated us well in terms of seating. Service was good. Staff was super friendly and we had a lovely time here. Food was yummy. Ramen was heavenly. Quantity is quite a lot for Ramen dishes so sharing 1 between 2 would be better unless you have a good appetite. Side note: The Ramen comes with noodles/rice so no need to order extra on the side unless needed. Can't wait to be back here again!"

Service was fast, friendly, and very attentive, making us feel welcome from start to finish. Great food plus great service equals a spot worth coming back to again and again."

The staff are friendly and service is quick. Most importantly the food is always excellent. Nice rich broths with plenty of choice."
