Hello from the Boston board. I am off to Hyannis for a week and looking for places for breakfast (particularly close to Hyannis) and dinner (willing to drive 30-40 minutes). Not necessarily the best meal you've ever had, but good, reliable, fun food. For example, we love the Flying Ace Cafe at the Chatham airport for breakfast.
On my list from other posts:
In Hyannis - Eclectic Cafe, Alberto's, Preta, Naked Oyster, Misaki, Palio's. Mixed reviews on Island Merchant
Further afield: Joe's Dinner (S Yarmouth), Beacon Room (Orleans), Red Pheasant (Dennis), Red Cottage (Dennis), Great Island Bakery (S Yarmouth), Ocean House (Dennisport), Sesuit Cafe (Dennis), 28 Atlantic (Chatham - at Wesquasett Inn?), LaCucina (Falmouth).
Comments on these welcome. other ideas even more welcome.
