I don't know the Wegman's in NY at all, but the one I used to use in the Boston area was ... okay?
It was a good grocery store with decent produce, a good frozen section, some nice specialty items, and some decent prepared meals. I would put it at roughly the early-2010s era of Whole Foods with slightly better prices. Now that I'm no longer working near there, I don't miss it much.
So I've never understood the hype. But I've also been told that the Boston stores were pretty mediocre compared to the ones in NY and especially Ithaca.
NY State vs NYC mismatch here. I expect nobody in NYC goes to Ithaca for groceries... :)
If you live in MA the standard options are Star Market and Stop and Shop, right? New England supermarket chains are already perfect.
I think the comment you are replying to is playing up a specific characteristic of, like, deep-in-the-city NYC (it looks like Wegmans has a place in downtown Manhattan?). I also read it as slightly tongue-in-cheek. People in NYC know what grocery stores look like, I think. They just don’t fit in dense areas.
