My family has been going to Rehoboth Beach for years and every summer one of the highlights is multiple visits to Thrasher's. Although maybe not the healthiest meal, it is a "must do". Their fries are the best I've ever had and whether you like them with or without vinegar, it's a treat regardless. Do not miss a stop here, and buy a bucket if you have 3 or more fry eaters in your group. It's appropriately priced (not cheap but you get a lot), and you'll be surprised how quickly they go!
