Outdoor Dining in January?!

Since it was about 60 degrees in Manhattan today, I had dinner at Shake Shack! Oh. Heck. Yes. They have the best burgers in the world, and I don't care if they usually come out looking like someone sat on them. Seating is currently limited, as they're digging up part of the seating area to install heaters so the Shack can stay open all year round. They might not even need them if the weather stays like this...yay for global warming?
