Grassy Hill Country Club - Orange, CT - I've been there for buffets before, and they were decent and for Easter they have the Bunny come as well for the kids. It's been renovated.
I love the buffet at Great River Golf Club in Milford; however, I think the price may be higher. The hall is so nice and bright there, it is perfect for an Easter Sunday.
Check out La Luna in Branford. Their brunch is always highly rated.
And finally, I enjoy the brunch at Bear & Grille in Orange, CT; atmosphere is good, and their brunch is better than their regular food which is blah.
