Gourmet Burger Kitchen (GBK)

Gourmet Burger Kitchen, widely known as GBK, is a burger restaurant chain founded in London, England, in 2001, with branches across the capital and other United Kingdom towns and cities. The chain helped popularise the idea of a sit-down burger restaurant with better ingredients than fast food, and the menu is built around hand-pressed beef patties served in brioche-style buns with a choice of toppings. The classic burger is the baseline order, and the avocado and bacon burger is among the popular variations. Chicken, lamb and plant-based burgers are also available, with salads, sides such as fries, onion rings and sweet potato fries, and milkshakes completing the menu. The restaurants are casual and informal, with simple wooden furniture, open kitchens and an easy, family-friendly atmosphere that attracts students, shoppers and groups. Noise levels are moderate, and there is no dress code. Service is typically at the table, and most branches accept walk-ins; larger groups can often reserve in advance, particularly at weekends. Drinks include soft drinks, milkshakes, beer, cider and wine. Prices are mid-range for the United Kingdom, with burgers costing roughly £11 to £16 and a meal with a side and a drink typically coming to £15 to £25 per person. Many branches offer deals, set menus or kids' menus, which can reduce the cost for families. Hours and menus vary by branch, with most opening around 11:30 and closing in the evening. Weekday lunchtimes and early evenings are generally quiet, while Friday and Saturday evenings can have waits at central sites.
