This place has great ice cream. Dusty's has your basic chocolate, vanilla and strawberry ice creams in wafer or waffle cones and a decent variety of hard ice creams including frozen yogurt. Lots and lots of toppings give you endless combinations. There are sundaes, shakes, icees, floats and other specialties such as ice cream pizza.
Dusty's has hot dogs and a few other non dessert items.
They have a drive through which makes it convenient with a carload of kids but be warned... Westerly is a beach town and in the summer it's hard to zip in or out of anywhere. Dusty's is frequently packed and the parking lot is no where near large enough. However, for the next season they will be moving to a different location, so hopefully, parking won't be such a nuisance then.
