I was here on the weekend for a work Xmas party - full venue booking. Great service, pretty good atmosphere. Nice range of craft beers available, as well as ciders, non-alcoholic drinks, etc. Good selection of finger food made available for the function, thoroughly recommend. The venue had organised a DJ as well - the volume was a little bit high initially but appropriate after everyone had loosened up a bit.
All in all, Hightail is a pretty nice place. Would recommend.
