One of the local media groups had a poll for the best Sunday carvery a few weeks ago. RH won it, Sportsman came 2nd and Punch & Judy came 3rd. I've been to all 3 and my favourite is The Sportsman.
Caddy Shack doesn't do a carvey I dont think, they do plated roast meals on Sunday. It's a great little pub with good food, though like Punch & Judy (which is across the road from it) it's a bit off the tourist trail.
