Actually passed a storefront location that went out of business recently. The location is perfect, their business was not, was some ice cream place.
Its in a high traffic area on the campus of Towson University. I think it would be perfect for an English style pub with unique English cask ales, flat screen TV's showing Premier League ball and Rugby, and some good English pub fare (oxymoron right).
It would be a niche market bar but I think it would do well, there is nothing like that on or close to the campus and I know the crew of athlete's I use to hang out with back in college would have loved a place like that. Add in some darts, pool, beer pong tournaments, flip cup, etc. I'd like to open a bar like that.
