246-248 Great Portland St, London W1W 5JL · Japanese restaurant, Asian restaurant, Health food restaurant · The West End

Reliable fast-casual spot for fresh, healthy Asian bowls and sushi with consistently friendly staff; expect kiosk ordering, quick service, and occasional operational hiccups at peak times.

Why this grade

itsu delivers solid fast-casual performance through fresh, reliable food quality and notably warm, attentive service that consistently exceed typical quick-service standards. Exceptional speed makes it practical for busy London lunches, though the functional, bright setting and occasional peak-time execution gaps prevent grade A territory. Strong loyalty and positive recent trends confirm this is a dependable neighborhood favorite rather than a destination.

The full picture

Set on Great Portland Street, this fast-casual spot feels bright and clean, built for quick lunches without skimping on freshness. Staff are frequently called out as warm and helpful, with one diner noting the team "made a hectic group order feel easy." Expect kiosk ordering and speedy handoffs. The cooking leans approachable and health-forward rather than theatrical: think salmon bowls and miso, sushi rolls, and Thai-style curries that taste fresh and satisfying. It suits office breaks and gym-goers who want something light but filling, with clear allergy info and protein-heavy options. Families do fine here thanks to simple flavors, rice bowls, and sushi basics. While there is no explicit kids menu, choices like teriyaki-style bowls and mild rolls are practical kid picks; just note the fast-casual seating and kiosk flow during the lunch rush.
