I used to live in Chicago and have been to Steamworks several times. I've also lived in several large cities throughout the USA that have its own BH's. Steamworks is leaps and bounds ahead of the others. Especially the Chicago location.
You'll find people of various ages, sizes, races, roles, etc... Weekends are definitely busier and it now being pride month, the weekends are going to be very busy. This can be good or bad based on what you want.... but when I have gone during these very busy weekends, it's been extremely fun, if you catch my drift!!
Definitely worth experiencing.
