Made in peanut oil (watch out kids with allergies!) these are seriously the best french fries ever, and I look forward to them every year on vacation! It may even be my favorite thing about Rehoboth! Don't look for ketchup, that is a big no no at Thrashers, just salt and or apple cider vinegar. They are crispy fries with loads of flavor... can't even put into words how awesome these are! Wish they had Thrasher when we were in Atalntic city!
