Curious, what is WaWa. Is that a real store name or nickname?

I spent almost every other week in Newport (Jersey City) between August and January and about 1 week a month before that between June and August but don't remember anything with that name or that could be shortened to that -- but then life was a two block walk up Washington Ave. at 8:00 am and back down to the hotel at 9:00 pm.


Maybe it is something I should recognize but I have been up all night and my mind is not quite as sharp as it should be at this point.
