DH and I want to come for three full days and do the drive from Boston to Acadia NP and back and stop as much as we can to eat as much lobster (oysters for me) as we can. We love casual and don't really want to "dress" up for those three days. It appears it is easy to do. When people talk lobster rolls, are they talking usually the mayo ones. We are not fans of that and want the warm buttery ones. Do most lobster shacks/places serve both and is there a proper name? Realistically, I need to do some mapping of driving route and turn off/stop off points. We don't mind grazing and sharing all day so we can taste more. Will we get our fix in three days?
The traditional Maine lobster roll is with mayo. Some places do butter as well. Two in the Portland area: the Bite into Maine food truck in Cape Elizabeth by the Portland Head lighthouse offers a Connecticut style (with butter). 2nd is Eventide in Portland. No better place for oysters and they offer their lobster roll with butter (I haven't tried it - it's served on a steamed bun. Looks good.)
Edit to add. Every place is casual in Maine.
Do you need to go as far as Acadia? I think you can get your fill without going past the Bath/Brunswick area. We really liked the lobster place in Cundy Harbor last year (see the Harpswells east of Brunswick) but I don't recall if they also had oysters or lobster roll with butter. Really nice scenery. Enjoyed the Bite into Maine food truck last weekend. There's picnic tables around the park but bring bag chairs to find your own spot in the shade. Waterman's near Rockland remains our favorite for a lobster dinner.
