When were on the tv gusy i always go to sports cafe in sauchiehall street,has a good arsenal support and they are fine with you wearing football colours,all other big sports bars dont let you in with colours.
Theres also PJ Champs in West End which is the official pub of Arsenal Scotland supporters clubs,this has a MASSIVE gooners crowd in for tv games and will be buzzing the day of the game but you'd need to leave here about 2 hrs b4 kick off to make it to game on time
does it open during the day,always seems to be shut when i go by.what was it called b4 joes was there,remember it was a great wee place but always loadsa trouble so council shut it down.
