The location has been home to such places as The Living Room, The DeLux and The Bleu Note. I don't think it will be changing any time soon, not the way these guys run a bar.
There is a wall that splits the bar in two and I am not sure of its function. Perhaps it simply holds the roof up but it looks like it takes a lot of space away from the already small bar.
I only noticed the one flood, I don't think there is an upstairs like ATG but I could be wrong on that one.
The main thing is the beer, that's what you are going for after all. As you would expect, they have a fantastic range of kegged beer on tap and barely a drop of macro stuff to be seen, except Blue Moon (Coors) and this is a decent enough beer to be honest, at least on tap. I don't care for the bottled version much. While I might not drink Blue Moon, enough people will and it has flavour unlike many other mass produced beers.
Another feature is the food. I very much enjoyed my fish (hake) and chips. The fish was as soft as air and the mushy peas were lovely and generous. The chips (fries) came stacked like a game of jenga, the big slightly overdone almost potato wedge type I love, similar to the Bull and Castle. I should have taken a picture actually. Actually a game of Jenga using such chips intrigues me....
