Coffee Shop has been around for a very long time, and it’s open 23 hours a day. It’s also more of a diner than a coffee shop, and they do everything from tacos and wings to meatloaf and salmon. And if you’re looking for breakfast at 5pm or 2am, you can get that too. Overall, the food is pretty solid and normal, and it’s a handy place to know about. It’s right off Union Square, there’s plenty of seating (including outdoor seating in the summer), and it’s a good spot to eat with a friend or have a meeting.
