We finally made it to Andy's to check out their custard. They offer vanilla or chocolate custard, with a large variety of mix-in combinations. You also have the option to create your own combos as well. I am a sucker for cherry sodas, and mine was very good. There is a walk-up window where you order, plenty of spots to sit and eat, and a busy drive-thru.
My only hesitation is that it seems more expensive than other custard places. (Culver's, etc.) It cost my family $22 for a small cherry soda and three small concretes. The small sizes are an ample portion though. I'd try it again!
