Macdara's Grille, which was in the Squire's Rock Creek Chophouse space after Squire's closed, appears to have closed in February.
I noticed today signage on the space for Hakuna Matata Grill, which bills itself on its Facebook page as authentic East African cuisine (but judging by the page not necessarily or not only Ethiopian). I didn't notice if they were open, but also judging from the Facebook page it looks like not quite yet. Their website is still under construction.
