Take the WL boat over and hit Geyser Point QS, the open-air lounge at WL. We've had some icky food at Roaring Fork, the main QS. Skip it. My waffles were gooey in the middle once.
Excellent sandwiches and snacks at GP. The bison burger description may sound weird, but my picky DH said it's deeeelish.
We also like Gaspy's at the GF. They have some tasty salads in the cold case there. DH said the Cuban was pretty good, and he grew up eating those in NYC. High praise from him.
Menu is much more limited than pre-pandemic but better this year than when we were at the GF 2 years ago. Used to be open 24/7 but now from only 6:00 am-midnight. Still a good place for food or snacks late-night.
The boat ride from MK/GF is short and a good way to cool off.
