Gamblers General Store has everything a gambler needs! It's a great place for tourists as well, because they sell old card decks and dice that you can buy for an affordable price and bring as a souvenir from your favorite hotel.
They served breakfast here too. Tried it out, but the food was okay. Only reason I am taking off a star.
Otherwise, this is a great place to buy some gambling related stuff. For those trying to learn, they have a variety of different books about almost every casino game. Many are useful and teach you different approaches and techniques on the games.
