I've only read about this stuff. It's supposed to be awesome. What a nice gesture by your boss. Good way to mark a birthday and a Friday.:)
There are several stores in Manhattan and Brooklyn that sell pints of this goodness. Go to www.jenisicecreams.com/pages/retail-partners.htmk#NY and see if there's any place close to you. I recommend Salty Caramel. It's my favorite, hands down. I think you will love it.
