Did an online order for pick up, got home and only received half of my order. The half we did receive was horrible. Not to mention the lady working the front when I walked in seemed very cranky and didn't even greet me. Called in for a refund, was placed on hold for 10+ minutes so had to hand up and call back. Would not recommend this Denny's.
Also, I tried submitting a review on their website with the link they sent to my email but it wouldn't actually let me submit it.
