I took a quick small look at the Snail & Newt Tavern and it's Tavern Cellar and saw that it's interior design on both rooms are similarly borrowed from many of the Tavern interiors from Skull Island. I feel these interiors on both of these rooms need a good renovation. Please look it up and change the interiors on the Snail & Newt Tavern's rooms with new unique interior rooms that match the Marleybone theme, just like many of the buildings' interiors. Note, the Taverns in the sewers don't have a basement downstairs built for it's cellars.
Also, to add, the music in that Tavern's cellar is playing one of the Skull Island themes in many of it's towns like Port Regal and Flotsam, instead of one of Marleybone's themes. Change that, too.
