That really, really depends what neighborhood you live in. Bakeries and especially butchers don't exist everywhere, and sometimes they (bakeries) suck. It's not Paris or Rome. And the prices are high in the expensive neighborhoods (and that's driven by proximity to offices in Manhattan and downtown Brooklyn). Some neighborhoods are both densely populated and a desert for quality, leaving only bodegas and overpriced artisanal boutiques.

I'm with the original poster here about Wegmans. In London you have Waitrose, which is 10,000 times better than Trader Joe's/Whole Foods and has fresh bread, alcohol, a butcher, etc etc and way more all in one place.

NYC is gar-bage when it comes to groceries.

If you spend a few minutes in the suburbs, even a rural exoburb outside of NYC, you'll drive to the supermarket and take a deep calming breath. You're not supposed to say driving could ever be better than a walkable city, but if time is precious to you and you value not hauling bags back and forth across multiple stores, you'll be way way happier.
