My best London girl treated me to an afternoon of shopping, eating and drinking this weekend and suggested we try out Wahaca in Covent Garden. The Mexican "market food" restaurant chain, founded by MasterChef champion Thomasina Miers, offers authentic Mexican food, a sustainable ethos, and a quick and easy eating option at various central London locations. In keeping with the idea of market eating, street food is freshly prepared and served to long tables with benches as and when its ready, creating a tapas-style meal. The menu features just enough different dishes to keep everyone happy without laboriously reproducing the Mexican "classics" like other chain restaurants tend to do. Big plates are also on offer, if sharing isn't your style, and an extensive tequila-themed cocktail menu is on hand to whet the appetite along with a tray or two of tortilla chips, salsa and guacamole.
