Quad East is much more spacious than its King Street counterpart. The feel is still that of a club with loud music and lots of lighting options that the instructors frequently switch up. They also have a yoga/pilates studio upstairs for bootcamps or post-ride core work.
Change rooms are upstairs and (the ladies' anyway) is clean and complete with showers and lockers... don't be thrown off by the 'private' on the door, a leftover from whatever this building used to be.
I can't say I loved the music my instructor chose on my first visit to this location, but she did say she will take requests in future weeks. She was very helpful and attentive to those who needed assistance and/or water during the class.
