"Walking inside Grumpy’s is like walking into a museum dedicated to Ketchum’s drinking culture. The walls are lined with old beer cans, photos of customers come and gone, past ski run signs, and bumper stickers that say things like “Licked it, liked it.” They serve up a simple lunch menu of burgers and fries with token vegan and gluten-free options—a real sign of progress in a place that's mostly had the same menu for decades and only installed a phone in the last few years (really). The $3.50 corndog is the best lunch deal in town, while $7 will buy you a 32-ounce schooner of beer. Grab a seat outside on the patio and drink in the sun with friends, and make sure to give a few pats to the regulars’ dogs who wander about. If you’re seated inside, pop some quarters in the jukebox and play “Sweet Caroline”—you might just have a movie moment as everyone explodes into song." - Hayden Seder

Not bad, but not the best burger either. They grill the burgers on flame, so the patties have a bit of a flame grilled taste. But they are not as juicy as I had hoped. The wings and fries are average too. The people here are really really nice and the atmosphere is really fun too.

Fat burgers! Low key spot. Friendly, down to earth staff. Definitely great place to hang. In addition to the 32oz schooners, pitchers of beers can be ordered, just not on the “green menu”.

Cool small bar vibe with a ton of character and fun staff. In from Detroit and would recommend it to any of my SE MI folks looking to chill in a friendly spot. 32oz mimosas ain't bad either.

Grumpy's Bar in Sun Valley is a great little dive bar with loads of character. It's the perfect spot to kick back with a good burger and a cold drink. The burgers are solid—juicy, flavorful, and hit the spot after a day of adventure. What really stands out is their excellent selection of local beers, giving you a true taste of the area. Laid-back vibe, friendly service, and no frills—just good food, good drinks, and a good time.

The ahi burger was great. Very crowded and mostly outdoor seating.

We came here and had a great meal as a family. The burgers were cooked perfectly. They had a nice charbroiled flavor. The guy helping us even put the game we wanted to watch on.
