Sweetwater Cafe is located in the Silver Legacy Casino / Hotel. I have eaten there on multiple occassions and no matter what I ordered, I enjoyed them all. There aren't many places that provide such great experiences. They have quite a menu varying from breakfast food items, sandwiches, entrees, specialty items like Bourbon BBQ Short Ribs and also offer Asian cuisine.
