Not that I have a lot of experience or anything, but ..... it seems to me that pubs in Europe are different places than bars in the United States. Still in other ways, these places are very much the same, and I am sure we'll see plenty of bars here too.
Be that as it may, the drinking age in England is indeed 18, so even our host agency plans social events at the local pub for us "global citizens," and if you think there are lots to choose from on the Main Line ..... well just imagine.
There are lots of choices that anyone planning to study abroad has to make. While it helps that Villanova GCPers have already been in class with each other for a semester, we only have impressions of each other. Assumptions are easily made, and "going along, just to get along" is an easy decision - but maybe not the right decision for everyone.
