So the current rumor for the former New Reservoir Market at 1st &U Street NW is that the street-level will become a liquor store.
I am not sure that the grandfathered use a convenience store carries over to a liquor store.
It is zoned R-4 / RF-1 -- not commercial -- so perhaps a zoning map amendment may need to be pursued. Similar to the process that Big Bear Cafe went through.
Of course, the rumor could be altogether false.
