This is one of my favorite places to eat in all of Las Vegas!
My usual -
Half dozen oysters, and a combo pan roast (spicy # 6)
There is only counter seating at the Oyster and it is located on the casino floor next to the Broiler.
More than likely you'll roll up to a line, but don't bail! It's so worth the wait, and the wait can be real long! There are no reservations to be made, and there are maybe a total of 12-15 seats at the counter. Since it's now open 24-7 you can often time it right and not wait that long.
The food is always dead on, and so comforting. Big chucks of seafood and a scoop of rice in a tomato based giant bowl of goodness.
Dining at the Oyster Bar is always fun. JJ one of the cooks, has been there forever. They make your food, and shuck the oysters right in front of you. As an added bonus, there's always some interesting, & crazy casino folk @ Palace Station to people watch while your enjoying your pan roast of choice.
