Each tart costs $4, but a value pack of 6 is $20.
You can order online and bake them yourself if you can't make it to the café.
The café is located in the downstairs dining area of Grand Central Terminal.
A few nearby places worth checking next.
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.
