At 10–12 Bloomberg Arcade, Koya’s City branch opens 11:30 a.m.–10 p.m. today. The menu’s Kinoko udon combines four mushrooms, hispi cabbage and walnut miso and is marked vegan; it is £16.70. Saba pairs smoked mackerel with mizuna, £15.60. Grilled tofu with leek oil and soy is another plausible small plate. These provide an alternative to the egg-led bowls; confirm broth and dietary details with the restaurant when ordering. This is a current-menu suggestion at an established restaurant, not an opening report. Exact branch, menu and hours. Sterling menu prices are preserved without an unverified USD conversion.
