I eat at Groucho's from time to time -- most often at the Forest Drive or Pawleys Island locations. (Curiously, I've never been to the Five Points original store). I never made it to this location, on Broad River Road at Intersection Center.
This particular strip of Broad River, with easy access from the Diamond Lane in the back, used to have quite a number of fast food joints. Some like Sandy's and Church's are hanging on. Others like Pizza Hut and Taco Bell have moved. Others like Taco Cid have simply closed.
The care someone took to line the old signs up with the checks on the floor is rather touching.

UPDATE 22 November 2011 -- It's now an Indian grocery as shown in this not very good pic:
