Cricklewood lunch [London]
It's not filled with options.
Depending on how much walking you want to do
Win Yip is a big chinese supermarket which also serves dim sum i believe.
Sushi Sey is quite well regarded if you walk down to Wilsden Green tube.
Lihiniya is a Sri Lankan place on the Broadway. I can't vouch for any of these places but if i was eating in the area i would probably go for one of them.
Lihiniya's pretty good. I had a decent meal there while the wife of the owner (and primary cook) was away and it was only alright. Not insanely stellar, but I know others on here have gone and found it to be amazing when the wife was in town.
I'd definitely give Lihiniya a shot, to be honest. The road it's on also has quite a few Iranian and Afghan places if I remember correctly.
