Review for Rio Hotel & Casino Review For SmashBurger Google User Jun 22 '18 at 23:15 I have been to this particular Smashburger location and another one in a shopping plaza at 5655 Centennial Center Boulevard which also has a Trader Joe's located conveniently nearby. My father, who never consumed large portions of anything in his old age, found the Mushroom Swiss Burger served by this franchise to be so tasty that he simply could not resist eating the entire sandwich - an extremely rare occurrence. Thus, also based on my own personal lip-smacking experience with this item, the Mushroom Swiss Burger comes highly recommended - absolutely delicious! View full site to comment or like
