Mac's is a great overall place to get food from. They have delicious hoagies, their pizza has a great taste, and their steak cuts are as good as you'll find anywhere. As far as the whole stolen recipe thing, are you serious? Unless you have weird taste buds, Mac's hoagies and East End's hoagies taste nothing alike... I know, I've been eating East End hoagies for years and have been eating Mac's hoagies since they started making them. Mac's are bigger and cost less, so there's really no competition, although East End's hoagies are still pretty good.
P.S Mac's mild wings are incredible. Try them out!
