Recommended bowl: Uni ramen

Open since April 2018, Maishi occupies the small alleyway space that was formerly home to the famous tori-paitan shop Kagari. Maishi is run by the Toratsue company, a restaurant group based in Tsukiji that currently has over 30 establishments across Tokyo. This is their only ramen shop though. The soup here is made with tai (Japanese sea bream) and kombu. It's 100% meat free. No MSG either. Officially the noodle supplier is a secret, but according to the shop staff they are delivered daily from Nagoya. What makes the spot special though are the toppings. The most popular choice seems to be the Sakura-Ebi Tai-Ramen, served with a sakura shrimp on top. There are also oyster and uni ramen options. The oyster ramen is served with fresh Hiroshima oysters. The uni ramen comes with scoops of sea urchin — three different varieties, in fact, which change daily depending on what is available in the market.
