Station Casinos recently acquired the Pams and immediately started the upgrades, smartly starting with the dining options. I've only been in once but that was enough to be able to tell that Lucky Penny is a significant upgrade from the previous 24 hour cafe.
Location is a bit hard to find with limited signage around the property- from the sports book entrance, it's all the way in the back to the right, around an awkward corner. Hopefully the lack of signage will be addressed because there was hardly anyone here when I came by, likely due to simply not knowing it was there.
In any case, the menu has a lot to choose from without being overwhelming. I sat at the bar and chose the waffle grilled cheese, served with tomato bisque. Order was out in a reasonable amount of time and the dish was delicious. I wanted to add on a salad but the server who helped me said the portion was large and very filling- she was right. The sandwich was large and the cheese was gooey, the soup served warm for dipping with just the right balance of sweetness. I would get this again, but I'll probably come back for the Benedict and the Cinnamon Roll pancakes.
TIP FOR SOLO DINERS: Sit at the bar. There's a TV and USB chargers for your device, as well as individual lamps if you're a food photo person.
