The Java Grande in Ellicott City appears to have closed, and it may be replaced by a pottery store that serves coffee. (Update: See below that it will be replaced by a pottery store.)
I haven't driven past the coffee shop on Rte 40 near Rte 29, but I have heard from a commentor and from one of owners of the Pottery Stop in the same shopping center. Lisa N. had previously said that the Pottery Stop hoped to take over Java Grande's space. They were planning to sell coffee, snacks and desserts -- along with the "paint-your-own-pottery" that they do now. Lisa N. says now that they hope to open in the new space in March.
(Update: You can read the Pottery Stop's announcement here. They'll run a full coffee shop and aimed to open early in March. Thanks to Jess for the comment below.)
Java Grande has a Facebook page, so you could follow that to see if they announce other news.
