Reviews of R'Délicieux describe a French-style chicken taco with a gratin topping and Algerian sauce, with some diners finding the portions huge and satisfying enough to eat during a work lunch and even take home leftovers, while others report inconsistencies in meat quantity and sauce, including tacos that seem grilled too long, have little meat, or taste different from expected; the beef is sometimes noted as tasting lamb-like. Service is described as very good by several, and one diner mentions receiving free fries and drinks when the order was placed for themselves, though there is caution that ordering via the app may not be ideal and on-site clarification with the owner helps. There is confusion about mini tacos versus regular tacos, and about substitutions versus the BBQ sauce that is offered. Overall, impressions are mixed, with some praise for portion size and service and some critiques about value and consistency.View restaurant profile
