The soft-serve at this cash-only place has been on my list for every visit to Chincoteague for many years now.
They don't do any other kind of ice-cream-- and soft-serve is one of the few ice-creams I crave. Good sized portions for modest prices (typical beach ice cream prices are silly high). The GF's caramel-chocolate sundae was under $4 and too big for her to finish. Generous caramel and chocolate sauce.
Nice outdoor deck, and a drive-through.
