A concept that works very well in college areas that I've seen is called "Snakes and Lattes". Basically a coffeeshop that has plenty of seating for playing board games. I've seen it work with bubbletea places as well. Seems to drive a lot of traffic by word of mouth due to its cooperative nature.
One issue with this is that selling board games suffers some of the same issues as selling books. It is very easy for someone to buy one online for very cheap. Plus there isn't as much of a secondhand market.
In addition in the area there are a few stores that sell board games that are already established. Off the top of my head I can think of two in Cambridge. Pandemonium Books and Games and Games People Play.
