Fritz's Frozen custrad is truly the best. I have been eating it since I was a kid and there is nothing like it. Their custard comes in regular or light. I always get the light and its delicious (you would never know its light).
I have tried many things there including sundaes, shakes, and concretes. My favorite of all is the Fritz's turtle. A turtle is vanilla custard topped with hot fudge, caramel and pecans. It is so good! If you are ever close by, definitely try it!
