"Lots of college kids"
I’ve lived on W 113th st for a few years. It consists of three Columbia dorms and a few Columbia frat houses. It does get noisy at times, especially during weekend nights when lots of frat kids are partying. There isn’t that many local businesses on W 113th st. The notable ones include Symposium Greek Restaurant, which is visited by a lot of locals due to convenience, but I personally don’t like it. There’s also Nussbaum and Wu, a bakery and café which is fairly overpriced, but has decent food.
