No, not Stations or any other casino! Carl's Jr., which has locations all over town, including five within walking distance of the Strip, has the "Cali XL" available for $5.99 and $2 more for fries and a drink.
The burger is tasty and MASSIVE. It makes for a better meal deal than the cheap casino burgers because the drink will set you back $3-4, making the true cost of lunch over $10 with tip.
For those unfamiliar with Carl's Jr, it's the West Coast version of Hardee's.
