Introducing MITSU - Where East London Meets East Tokyo - Opening Early 2026

MITSU launches a bold new restaurant born from the collision of East London's vibrance and creativity with East Tokyo's neighborhood izakayas. MITSU cuisine blends the authentic Japanese craft of Robata fire and razor-sharp technique with the energy and attitude of Shoreditch - all designed to be enjoyed together.

The izakaya bar brings high energy with crafted cocktails and daily vinyl and DJ sets to toast the night with flowing sake and mizuwari tankards. Transport yourself into an experience - whether it's post-work drinks, laid-back lunches, refined dining, or late-night revelry. We also have a couple more surprises we can't wait to share with you.

MITSU: the conversation between two cities - where tradition meets edge - sparks will fly.

Opening Early 2026 in the heart of Shoreditch
