What's not to love at frozen custard? It's creamy and delicious. Nielsen's is a great spot for frozen custard.
They have multiple ways you can get it - concrete, sundae, etc. - and multiple mix-ins and toppings - from fruit to candies to syrups. On our most recent trips we did a concrete with strawberry custard with cheesecake bites, maraschino cherries, and chocolate chips. Yum!
It's a small spot in strip mall. It's never too crowded. There is some seating and cute decor. In addition to ordering your own of whatever you want, they also have pre-packed concrete in some of their most popular flavors so you can just grab and go.
The main complaint here is the staff. No mistakes or anything. But it's like every single one of them hates their job. Which, while that may be a valid feeling, it'd be nice to not radiate it quite so much.
