Waffle Crush is super great! They park at a school near my house about once a week and my two year old (who doesn't say many words yet) learned the word "waffle" after his first visit.
The waffles are uncomplicated and hot. Little chunks of sugar are found crystallized throughout the waffle which is amazing and they have so many different combinations to choose from for toppings.
I usually go with the standard banana and Nutella toppings, but they have a Biscoff topping that you have to try before turning your nose up at it. You probably don't even know what Biscoff is so why not try it? Biscoff are cookies that are ground up into a spread - it's cookie spread! It's amazing; try it.
On New Year's Eve, my wife found out that Waffle Crush was open until 1am and we drove 30 minutes out of our way just to stop by and get some waffles. They are that good.
They do take credit cards which is great; they have an iPad with a card reader so as you order, they will punch your order into the iPad, it gets sent automatically to the chefs in the truck, and they run your card. It's super easy and convenient.
I would recommend ordering your waffle in a to-go container. It's a little bit easier to manage and if you don't finish the whole waffle (they're pretty small anyway) you can close it up and take it home with you.
