Don't pass this place up. Yes, the oyster bar is an unassuming counter with only 18 stools in a smoky local casino, complete with slot machines ringing behind you. They don't take reservations so you have to hope they're not busy.  However, the pan roast here is DIVINE and the chefs and waitstaff (especially Dolores) are a hoot. Every time I am in Vegas, I come here for the mixed seafood pan roast. The seafood is succulent and not overcooked, the sauce is rich, creamy and flavorful. I have had other dishes, such as the linguine and the gumbo, but I still prefer the pan roast. It isn't possible to finish a single serving yourself, so either bring someone to share it with or prepare to have leftovers for lunch and dinner the next day. In my opinion, eating the pan roast is worth the minimally increased risk for cancer from the second-hand smoke (haha).
