I love that there's a museum dedicated to American art, founded at a time when American artists were underappreciated. The exhibitions are curated with a broad but discerning eye, and the architecture is spectacular. In my experience it's typically much quieter than the obvious choices like the Met and the MoMA - although both are remarkable, there's something I love about the scale and style of the Whitney.
A living archive preserving history and promoting scholarship of grassroots urban space activism by researching and archiving efforts to create community spaces. They also exhibit materials that document these actions, to educate people on the political implications of reclaimed space.
Seasonal salads, sweet and savory treats, and great coffee. It's probably my most common lunch spot when I work from home and they also offer catering if I'm too nervous to cook but want it to feel homemade.
