The Avro is a pretty relaxed, comfortable place to go for a drink. We decided to try it out Friday night - getting there for around 8pm it was already pretty busy. The bar is quite small with a couch at the front, a few tiny tables that sit 2-3 people and plenty of seats going along the bar. We were able to get a seat no problem but if we'd shown up at around 9, we would have been out of luck or needed to squeeze in on the barstools.
As I said the place is much smaller then what I thought from the photos I'd seen. Don't let that deter you though! The Avro just might not be the venue to go if you have a large group. For 2 to 3, it's quite cozy and intimate with a great atmosphere. Eclectic decor throughout, and warm low level lighting.
The bartender was really cool, very attentive and aware - so saw my short self struggling to be seen behind all the people sat at the bar, and was able to get my order through quickly. The beer is cheap and good, just how I like it, and if you're feeling peckish they have birthday cake.
Apparently cheap pint nights on Thursdays if you show up in plaid and lots of events and live music regularly going on. If I lived East this would easily be my local and I plan on going back again in future when in the area.
