Formerly a working law library, the 40th Floor at 190 S. LaSalle was transformed into a tenant lounge, bar, and private event space.

The Stacks bar and lounge provides tenants and their guests with various entertainment and seating options for working and meeting, and also serves as a pre-function space. The Library is an expansive, full service private event space with book-lined walls containing over 50,000 volumes retained from the original law library.
