I've lived in East Hampton for 20 years (grew up there), am now in NYC for the summer. Going home with a friend for the weekend to show him the place. I am generally not a huge fan of the sceney (Nick&Tonis, Pacific East [though I heard that closed]) restaurants. I like good, fresh food though, and assuming entrees are in the 15-25 range that's just fine.
My friend is vegetarian but I eat meat. I was thinking a few of my favorites from my research the last few years are:
Dockside in Sag
Matto in East Hampton
Nichol's in East Hampton (though this one is probably the least veg-friendly)
Other ideas/updates on these? Looking to show him a good dining time without ending up with a $250+ bill at Della Femina for four of us (mom+dad included).
