I live right across the street from Arefa's and so I tend to stop in when I am feeling particularly lazy. The staff is very friendly and I think they are still working out just how to run a coffee shop in the middle of the over saturated coffee shop market of Squirrel Hill.
However, it is always very clean, very open, and a good place to be. It doesn't have the same atmosphere of hip-trendy-cool that 61c does, but it is a nice quiet alternative.
