They are only open Monday through Friday and are not open on weekends.
The café is located on the lower level of an office building, so it can be a bit hard to find.
The location is hidden at the entrance to the subway at 72nd and 3rd, northeast corner.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
