Denny's is your all around place to dine when you just aren't up to getting all dressed up and heading out to your favorite five star restaurant. I admit, I've come to Denny's before in pajama bottoms and a tank top. The Denny's in Surfside Beach has to have the friendliest customer service out of a lot of places down here. Now, I only really come in the morning (early) so I'm only really applying this to the morning crew, but they are positive and bright and just about the most cheerful people you'll meet. The food is good too...definately try their Buffalo Strips with the Bleu Cheese Dressing...also, their omelots (like the ham and cheddar) are great as well. I'd definately recommend this to someone who's looking for some good food in a casual setting...places for kids and the elderly and the lazy, haha.
Pros: Service, cleanliness, location
Cons: Parking, rush hour, bathrooms
