The Queens Head in Brook Green is a nice traditional pub, been going strong since 1820…

Not been for a year or so, but I used to drink there every week when I worked nearby and they used to do a great fish and chips. It’s quite big inside and pretty close to CAP Euro venue
One option of many! :cheers:
