The best restaurants serving American food in Harrow on the Hill Harrow London

Waited a couple of mins to order even though there were no other customers waiting. Sat directly opposite the tills so that I'd know when my tea was ready. I wasn't aware you had ro collect your own order so despite making eye contact a couple of times with Arth who took my order - I got up after about 10-15 mins to see what was wrong. Then I realised my cold tea was sitting on the counter all along. Not a nice experience.
