After a 90 minute bicycle ride adventure:
Rakuraku in Kichijoji.
After a couple English lessons, a 45 minute bicycle ride, and a Guiness:
Botan in Takadanobaba.
The thing is, I really enjoyed both of these the first time around. Really really liked em. But this time, they were both lackluster. This happens a lot I've found. A shop is great in round one, but round two is a let down. Any theories?
A few shops have been stellar every time. Ones that come to mind are Ippudo, Ivan, and Bankara.
