The best restaurants serving Other cuisines food in England

Weird experience, went to the till right at the entrance to order coffee and cake to sit down, told to go and wait inside by the till for a "host to show us to a table". I did say "um…only want coffee and cake" but was told to wait there. Which we did. For ages. Nobody came so I stopped a staff member as she was walking past. She told us to go back to the till and order there which we had tried to do in the first place….so we did. Was told we had to sit in the takeaway area outside, even though there was a barrier dividing us from the nicer, bigger space alongside where people were having coffee and cake in cups and saucers……so we did. Took ages for the coffee to arrive - in paper cups - which is fine though not entirely clear why. We waited and waited for our cakes, in the end gave up and drunk our by then cold coffee. At least another five minutes before the cakes arrived in a box, and we had drunk our coffee. I’m not sure what went wrong here but was totally confusing, staff not clear and I don’t quite understand how they organise it. Trying to be fair here, and there might be a system but not clear at all what it was. I know it was newly opened but the staff seemed clueless. Won’t be going again sorry.
