Campus is pretty quiet now, and so is "The Library." The Library Cafe and Bar is a delightfully quaint little establishment on North Randall, next door to the Wisconsin Institutes for Discovery where I work. The inside decor looks like a library, and this pub has been a favorite around campus for many years. It serves great food too, if you'd like to partake in that.
I was planning on getting there by 5 PM if you have time to stop by for a little bit. There is parking in Lot 20 across the street, or underneath Union South. Hope to see you there!
