I can second Denmo's, they're really good.
Third for Denmos. In the summer, you can even get good whole belly fried clams there. There are not many places for those around. Good burgers and ice cream too.
The french bakery in Woodbury has some really nice breads and pastries.
Yvonne's in Southford is good for breakfast. I have a friend who lives right around the corner and is great at finding value spots, and he swears by it. I've been a couple of times and had good experiences.
The Charcoal Chef in Woodbury (up Rt 6 past Nonnewaug) is an institution. It was mentioned for best burgers I think in that thread. It's a place the old-time locals (my parents) rate highly. Simple, but well prepared food.
It's controversial I know, but I like Good News Cafe quite a bit. Many find it overrated. I've never had a bad meal there.
Take the ride across Rt. 47 to Washington for the GW Tavern and a little further over to Rt. 202 for The White Horse in New Preston on Rt. 202. Good, upscale pub grub at both.
The Painted Pony up the road in Bethlehem has solid 'Murican (with a side of Italian) food. Nothing exquisite, but tasty and filling. (Caveat - It has been a few years since I've been. It was a regular stop when visiting my parents in Morris.)
Enjoy living in God's Country!
