love the East End Market. We make a stop there on our way out of town (we usually have a rental return to the airport).
Some things to know... you can do preorders, way way more than the limit of 7 cookies at a walk up (need to do a day or two in advance at least).
It is a very different experience. Disney Springs has a lot of theming, and the theming is a nice part of the experience, especially if you have never been. The stall in the East end is very small... really just a counter, they do not offer coffee as there is a coffee place within the East End Market.
The East End Market has a decent amount of nice venders, so it is a little food hall basically... couple of floors We go there for a lunch and to grab some cookies when we head home. They just started allowing preorders of the coffee cake which is our fav fav fav.
