During the holiday season (or is it going to last?), Seven Dials Market has hosted many restaurants, in Food Court mode. Among them, Club Mexicana offers a fairly simple, but entirely vegan cuisine. The brand has several addresses, and within the Seven Dials Market, it is rather a fairly small corner that awaits you.
You order at the counter and are then called when your order is ready. It is a bit like a fast food, with no real service, but with recipes based on vegan Mexican cuisine.
You can choose your between the tacos and burritos versions (wrap or bowl for burritos).
