When Mac and Dee are looking at "Dylan's" Facebook page and notice he is shopping for a silk sash at Tootie's the profile picture used for Dylan is when he steps into Paddy's pub at the end. The background is that of the front door, dark green painted wood with the off yellow and mesh window behind him.
When Mac and Dennis go back to the gin bar (where all they serve in gin), as they walk in, to the left you can see a stock room with different types of beers.
