Kantoku-tei is a Japanese restaurant and tea house at the west gate of Koishikawa Korakuen in Bunkyo City, Tokyo. Lunch service offers only three set meals: premium hanakagozen, premium sobazen, and premium plum udonzen, along with a set of gold-flake matcha and Japanese sweets. Lunch begins at 11 a.m., and guests write their names inside and wait for a seat. Only a few seats are by the window, so views of the garden are limited.
