There have been a few mentions of this place on the New England board, but I felt that the Chart Room was deserving of a little real estate on the Boston board.
The Chart Room is in Cataumet (Sometimes referred to as E. Falmouth or part of Pocasset) in the vicinity of Otis Air National Guard Base. About a 1:15 ride outside of Boston (lots of back roads).
I will say that my dining experience here had as much to do with fantastic weather and good friends, but I'll attempt to be objective about the food.
On first glance of the menu, the Chart Room is a fairly unremarkable seaside venue. A good variety of sandwiches and seafood (I don't recall seeing fried clams).
We had stuffed Quahog, Steamers and Clams Casino to begin. All were pretty top notch (actual clam in the Quahog), but the steamers were a bit gritty... it happens. Luckily I was with friends that had been there before. There is a lobster sandwich that is not on the menu and 3 of us ordered that. My wife opted for the chicken salad over tomato, being epi-pen allergic to Lobster. The chicken salad was dayum good, served over a great vine ripened tomato, not the typical redish/greenish crappy commercial tomato. The chunks of chicken were large, moist, well seasoned and flavorful.
The lobster sandwich was recommended on Portuguese bread, slightly sweet, but not as eggy as Brioche and the bread appeared hand sliced. The lobster was lightly dressed with a good mayo and small pieces of celery. This was a huge sandwich, $25.00 and more than a value for the price. I kid you not when I say that more lobster fell out of one half of my sandwich while eating, than is often found in a typical lobster roll. I think Neptune Oyster and Johnny Ad's in Old Saybrook, CT has formidable competition here. I can't think of a time when I had to make a concerted effort to finish a lobster roll/sandwich, it really was that big. Sides of potato salad (good) cole slaw or potato chips were part of the meal.
We also have a few rounds of kickass margritas. After lunch we headed outside for some more cocktails. The view overlooks Redbrook Harbor, there are tables, Adirondack chairs and benches outside, and a window where you can order drinks.
The Chart room is a converted old railroad barge as the main dining area inside with an open, but covered patio attached.
I don't think I would have found this place on my own in a million years. I would certainly recommend seeking the Chart Room out if you are contemplating a lower cape excursion.
The best directions I could find are for getting to Kingman Yahct Center wherein the Chart room is located.
