I know I shouldn't expect much when it comes to fast food, but at the very least, if you're going to qualify yourself as a fast food restaurant, I should expect to receive my food...fast.
On multiple occasions, I've visited this specific Carl's Jr, and the experience has always been the same; slow. Not just slow, but painfully slow; slower than a snail racing a turtle through a track made of peanut butter and molasses. I can understand if you have a drive-thru line like In-N-Out with 15+ cars snaked around the premises, but I've sometimes been the only car in the drive-thru and have STILL had to wait for what feels like an eternity.
If my order was at least correct more than 50% of the time, then I wouldn't really have as much to complain about, but after waiting eons for my order just to have it be incorrect, I find that highly disappointing.
Be warned if you're deciding to eat at this specific location.
