There is an English menu online! We ordered the tempura, obviously — specifically Tendon 1. It came with a side of preserved veggies and a pot of green tea. We also got a bowl of soy-soaked rice with one each of prawn, kisu fish, and mixed tempura. It was pretty damn good. Note that this is the greasy style that is heavy and is supposed to be consumed with rice. There are apparently two styles of tempura. Later, we do hit up Tempura Tsunahachi in Shinjuku if you’re into the airy type of tempura(also severely overpriced). From my research, it seemed that most restaurants, high end or casual, now serve the airy type of tempura. This could explain why the line in front of Daikokuya is so long! We got there at a pretty lucky time so only waited for around 15−30m, otherwise I’d dock a star for the wait!
