I have never been to the location in South End even though I have driven through there plenty of time (on my way to the nail shop in the same complex). But recently I had to be at the Mecklenburg County Courthouse for various things, and since the closest parking garage is the one by this Cluck N Cup, I stopped in to get a quick bite (and to validate my parking ticket).
I like it, something about the big glass windows and sun shining in make it very peaceful. My first visit I ended up doing work here (armed with an iPad, free wifi and remote log in).
My go to breakfast item is their breakfast sandwish with ham, egg, cheese on toasted croissant ($3.99). FABULOUS! Their regular coffee is good too, not the watery kind but has a good robust taste to it.
They also serve lunch and are open on weekends. Quite honestly their price is very reasonable for being uptown.
P.S. Remember the parking validation is only good for 90 minutes ($3 worth).
