Went to see their new menu and got the new fried snack box, w'choice of sauces for each snack type: curly fries, mini tacos, onion rings & VERY GOOD chicken nuggets. They have like 10 choices of sauces. The Oreo milk shake was FANTASTIC!
The value is fine, because the price of everything is too high & having to pay crazy high staff salaries in the fast food market is ridiculous so it gets passed on to the consumer.

It was just a very clean location. Good help and good food. We only had the old school tacos. And real onion rings.
Parking: Large open parking lot.
Kid-friendliness: I believe I saw a kid menus that there wasn't anything there that the kid would not eat.
Wheelchair accessibility: There were no stairs to the building. And there was a wheelchair stall in the restroom.
