The best restaurants serving Spanish food in Harrow London

Went with my family. Lovely little bar and restaurant, we are quite the regulars! Ambience beautiful, food great! There were 6 adults and 2 children. As we were leaving a wonderful Evening we experienced something horrible,a couple with their daughter were being offensive and covering their ears as we were leaving . The exchange of words were horrible! It was horrible racist behaviour.we told the staff they didn't do much as management wasn't around. These people should be banned, if they cannot accept diversity in the world,let alone harrow.
