If you go to Sears Tower early in the morning (weekday), there’s little line and security is fast. The glass-floored platforms are unique, it’s different from just a tall building. All our friends and relations who come to the City, we take to Sears ( = Willis, ugh.)
I haven’t been to Hancock in a long while, but they have some sort of restaurant ($$$) on the 95th floor, IIRC.
Technically, not the original location. The original Billy Goat was near the old Chicago Stadium, and basically where the United Center is now. (The old Billy Goat was at 1855 W. Madison). It moved in the 60s to the Michigan Ave. location. But, yes, that is the famous Billy Goat and the only one I enjoy going to, because it’s a big journalist hang-out. (Although it doesn’t seem to be quite as packed with newspaper types, since the Sun-Times moved a bit west down the river.)
