“First opened in Fukuoka city in 1960 as Futaba Ramen, then renamed Ichiran in 1966, this now world-famous ramen shop first branched out with its second location in 1993 and the onslaught of additional branches opening hasn't stopped since.
Ichiran's famous Hakata-style tonkotsu is now known worldwide and can be tried at any of the chain's 50+ locations. Smooth, savory and quintessentially Hakata-style pork-based tonkotsu. This 11-story, company-owned building now serves as the Ichiran flagship.”

There is a lot of choice. One selects the ramen (no choice there), the size of the noodles and any extras like egg, onions. Etc. Then one gets handed a piece of paper where one can fine tune the ramen bowl. Thickness of the broth, extra garlic and spicyness amongst them. Even when the line is long the wait is bearable as there are many seats. The seat is more like a mini cabin where one sits and the waitstaff who you never see shoves the order items through a pigeon hole into your cabin.
The bowl is thick, as expected, the noodles cooked as ordered. I chose the spicy version (2 out of 10!) which gave it a nice kick.
Overall a pleasing experience.
