Part of W 120th st borders Columbia University. There is a street entrance to Mudd, the engineering building where you’ll find bathrooms you can use and a few vending machines on the first floor, even one for ice cream. If you need to use a computer, go to the fourth floor and there’s computers in the lobby area that you can use without needing to log in. There’s also stairs that lead to campus if you’re interested in touring Columbia. The other side of W 120th st between Broadway and Amsterdam borders Teachers College. If you consider the part of W 120th st that is west of Morningside Park, you’ll find it busy with a lot of students bustling around.
