The best restaurants serving American food in Grays Riverside Thurrock East of England

This is the 3rd time i have been there in last couple of Months and the service i have to say is terrible. it took them 20 Mins overall to take my receipt to the counter that i got from the machine and then serve me what i wanted and even then got one of them wrong {gave me two hot wings instead of the 3 i ordered}, and other 2 times i wanted a Variety meal and the woman behind the counter said because it wasn't on there machines i couldn't have one, but then when supervisor came after 10 Minutes of arguing , finally ordered one for me. Thinking of not going there again, shame is the branch in Aldgate , London is pretty good, but this lot are inept and basically shocking

first impression when i walked in, big and clean store. the service was quick and food still hot, all as i wanted
