I really think that a campus pub is a great idea. I know that it would draw me back to more basketball games. I don't drink much, but I like the option to knock a few back and I just like the atmosphere of pubs especially when they are connected to university life.
I had a friend who went to the University of Wisconsin and I remember going to their student union where they have the Rathskeller and then the Terrace outdoors on the lake during the warm months. It's just a really great vibe and a lot of fun. Of course, Loyola could do something great on a much smaller scale. Those sorts of things draw students and people from the wider community. A campus pub at Loyola could possibly even attract people from Rogers Park and Edgewater, and give Loyola somewhat of a 'regional' (or neighborhood, in this case) fan-base that state schools can sometimes benefit from. Loyola sports used to benefit from Catholic, northside residents coming to games and cheering them on, but I think this is changing.
I can just imagine a pub and cafe with outdoor patio seating with a lake view as part of a refurbished Crown Center. That would be fantastic. Unfortunately, it seems that a campus pub just isn't in the cards. Garanzini and the rest of the administration are extremely anti-drinking as it relates to the student body (despite Jesuits enjoying top-shelf malted, fermented, and distilled beverages

). A campus pub would run counter to the message that they sending undergrads. And it's been an effective message: Loyola does not have much of an undergrad drinking culture, at all.
The administration has made some interesting choices in making campus more of an all-inclusive 'bubble' in recent years. Don't get me wrong: I think what they have done is beautiful. I understand that part of it is safety and convincing suburban parents that the university is an oasis in the big city, but it has also cut out the local community. I know crime is still a problem, but the neighborhood is rapidly gentrifying (with potential basketball fans!). As an illustrative example, I always think about how the lakeshore trail effectively stops at Loyola and inhibits people from riding through campus and continuing up toward Evanston. Basically, cyclists need to jog all the way west to Clark.
