I've been several times. Great for a quick bite that's levels above fast food.
The burgers are nice comfort fast food quality. Taste is there. A little flat.
Fries are great, as they are fresh made; a touch of salt wouldn't hurt.
The onion rings do not tickle my fancy unfortunately. The balance of crunch to soft onion is not there. Too crunchy throughout. Over cooked onion in middle.
Like I said, great for a quick bite.
