What a pleasant surprise this place was! While my wife and I stayed at The Palazzo, my brother and niece stayed at Harrah's so, I found myself there a few times. Fortunately for me, a couple of those times were around lunch time and we wound up at the Oyster Bar.
Frankly, was not expecting much as Harrah's overall just seems a bit meh. The Oyster Bar was far from meh though even if only rating the quality of the oysters. They were ice cold, perfectly briny and served with some kick butt hot horseradish to add to your cocktail sauce. Ate 4 dozen between the two lunches. Also tried the seared tuna one of the days. It was good, not great like the oysters though. The only true downer was the clam chowder which was average at best.
If you're in the neighborhood and craving some oysters, hit this place and you won't be disappointed!
