I don't know what I was expecting, as I haven't had much experience with Carl's, yet not only are the burgers fresh, flavorful, and the portions generous for fast food, the service and attention to detail has been notably good.

And while I usually roll thru the drive thru, tonite I went inside, and the space was bright, clean, and the young fellow using a floor cleaner immediately turned it off in consideration, before the door had closed behind me. I also enjoy that the more exotic choices on the menu (hand scooped ice cream shakes, jalapeno poppers) have so far exceeded expectations. My fifth star is for how, every time I've shown up, I tangibly feel valued as a customer. Carl senior must be proud! read more
