Though it is possible to find Tsunahachi branches near the main shop (Isetan, Takashimaya, and Opera City), if you like tempura and want traditional ambiance, the main branch is the way to go. The main restaurant is close to the "Bicqlo" complex on the east side of JR Shinjuku station. If you don't have a reservation, expect to queue. The quality of the tempura is great and the fact you can watch the chefs in action is also an interesting experience for visitors. If you happen to be seated upstairs, be forewarned that most of the seating is on flat tatami so visitors with difficulties sitting crossed-legged/on their knees should request a first floor table.
