This Shinjuku branch of HealthyTOKYO is a fully vegan cafe with a unique focus on CBD. Located conveniently on the B1 floor of Shinjuku Marui (Connected to Shinjuku-Sanchome Station A1 exit), it offers a range of plant-based meals like sandwiches, lasagna and quiche. For something sweet, expect to find cheesecake and chocolate cake.
This Shinjuku branch is a good option if you're looking for breakfast as it opens earlier than other vegan options in the area. They also have branches in Harajuku, Daikanyama, and Haneda Airport.
