I, for one, am extremely happy about Costa coming to Marple, I love the Coffee and the decor and ambiance of the coffee shops themselves.
I personally think that it is a great move for Marple and will improve the appeal of the town giving it a more cosmopolitan edge. I also strongly belief it will encourage more high quality chains and possibly bars and restuarants.
Sad as it may sound, Iliterally can't wait for Costa to open!
