I lived in the SE PA area for years and Wegman's arrived in the
Downingtown area in the early 2000s. Not only do they have great hoagies...(yeah that is what they are called) but they have great all around deli, bakery, and produce sections, and lots of unadvertised specials that are really low prices on stuff that you would want to buy.
I miss them here where I'm at now, in the Southeast the competition among supermarkets is not to great so prices, quality, and service is poor to middling only Publix stands out, but it still is a bit behind Wegman's.
