Addis Cafe (Ethiopian) on 19th is apparently closed. I tried to go there today, and although the sign is up, the place was locked up and dark, and there were candy racks in front of where the buffet table was (as if the place is now temporary storage). Looks like it's been closed for a while.
Mi Casa (near 14th+Webster) has been closed the last few weeks. No idea if this is permanent or temporary; I know they were going to do some construction for the nightclub.
