For conveyor-belt sushi head for Yo! Sushi or venture a little further upmarket at Itsu, where the belt delivers up dishes from all over Southeast Asia. Groundbreaking noodle bar group Wagamama is still the business for huge bowls of ramen noodle soup in a canteen atmosphere, while there’s a more intimate vibe at pan-Oriental mini-chain Busaba Eathai. Venturing further west across the globe, Masala Zone has done for Indian food what Wagamama did for Japanese. Reaching Europe, you can’t beat Strada for wood-fired pizza, pasta and Italian staples. More unusual is idiosyncratic Belgian moules-frites specialist Belgo, while the dishes served at Giraffe span the world.
