German Doner Kebab (GDK)

All meat served across GDK UK locations is halal-certified, including beef and chicken. This is confirmed by the chain's own FAQ on Uber Eats and echoed by the MenuSpot page. The commitment covers signature meats in the OG Kebab, Doner Wrap, and Doner Krunch Burger. No independent accreditation body is cited, but the consistent official statement across multiple sources provides strong assurance.

German Doner Kebab offers a dedicated Vegetarian Kebab with a plant-based patty and fresh salad, along with sides like Chilli Cheese Bites and Spring Rolls. A Vegetarian Doner Box is also available at some locations. The chain's FAQ confirms these options. The kitchen is shared with meat, but the menu provides clear vegetarian choices.

German Doner Kebab (GDK) offers some gluten-free options, including the Doner Box (meat, chips, salad without bread) and the Doner Salad Box. The chain does not have a dedicated gluten-free menu and states that items may contain or come into contact with gluten, as the kitchen is shared. A coeliac-friendly meal was noted in a review. There is no dedicated fryer or kitchen, meaning cross-contamination risk is present. Confirming directly with staff and checking the allergen guide is advisable.

GDK offers a plant-based kebab (listed as OV) and other items, but vegan options are limited and require careful modification. One review from the Kingston branch reported that staff initially said nothing was vegan because the plant-based kebab's sauce contains milk. It could be ordered without the sauce. The chain's own FAQ notes that the Vegetarian Kebab contains cheese and may not be suitable for vegans. Customisation is possible at some locations but not guaranteed, and cross-contamination risks exist.

Several items contain dairy, including cheese on boxes and quesadillas, and in sauces such as the yoghurt-based and garlic sauces. A notable concern is that the standard sauce on the 'plant-based' (OV) kebab contains milk, requiring a request to remove it. Vegan options may be modified to be dairy-free. No dairy markings appear on the menu, and cross-contamination is likely in a shared kitchen.
