So. Good.
As everyone's said, CASH only. So be prepared going in.
The donuts are epically awesome. They are the perfect size, not overly huge but not too small either. The donuts have a wonderfully crispy outside but are light and fluffy on the inside. The glazes aren't too sweet and are flavored well.
I'm not a sweets person, but these donuts are amazing. I'm definitely spoiled now and Ronald's has set a new bar for donuts that will be hard to beat.
