We ordered food, starters came in time the main meal came approximately 30min after due to them having a glitch in the ordering system. Then I received my Eisbein and it was undercooked, so sent it back to have it fried some more. Then I had to wait 40min again without the manager coming to explain why it's taking so long. Really not a good experience and will never return to this Spur branch again.
