"We visited on Saturday 10/09/2016 whilst looking round the National Gallery. The restaurant was busy but by no means full so, as we were shown to our table, we told the waitress that we wanted drinks only and she confirmed that was not a problem. The waiter eventually came over to take our order which was nice and simple, 1 tea and 1 coffee. We waited for 45 minutes and nothing turned up other than a small jug of milk but people that came in after us were all being served so we left in disgust. If they don't want customers who are not spending a fortune then they shouldn't tell us it was fine to order drinks only. Its a shame because the setting was very nice and relaxing."
