Just that. I try to give my business to local stores but I don't really know of a place like this left on LI. Basically a non-chain version of Sur La Table or Williams Sonoma, and with more of a focus on really useful items than overpriced gadgets.
The closest I can think of is a restaurant supply place, but of course they focus on restaurant-type items. Some True Value stores carry kitchen items, but they're very limited (and are borderline chain stores anyway).
