Mr. Purple is the restaurant/bar on top of Hotel Indigo on the Lower East Side. They do lunch, brunch, and dinner, and there are two terraces where you can sit outside. There’s also a little pool. You probably aren’t going to swim in it, but it’s nice to know that you could. This place isn’t as cheesy as a lot of the rooftop bars you see out there, but it does get crowded. So, unless you come early, you might have some trouble at the door.
