The best restaurants serving German food in Middlehaven Middlesbrough North East

Update: Even more disappointed with GDK customer service. They offered a voucher to 'help make it right for me,' but they never delivered on it. I had an unpleasant experience at the till after ordering the Doner Box, which, according to the menu, includes three dips. However, it only came with one dip. When I asked about the missing dips, I was told that the box only comes with one and that the ordering machine’s information needs updating. Unfortunately, I had to pay for two additional sauces that were supposed to be included. Disappointing and misleading.
