Grumpy's - Hamburger restaurant in Ketchum - 860 Warm Springs Rd, USA

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.

Despite being a busy local hangout, there is nothing to write home about this place. The burger is as absolutely generic as possible. The fries were under cooked without any flavor. The atmosphere was hit and noisy. Fry sauce was mayo with a little bit of ketchup poorly stirred together.

This place is a classic. No-frills, delicious burgers in a perfectly kitschy eccentric space. The service is friendly and appropriately offbeat. Great selection of draft beers - make sure to get the 32 ounce, which is basically served in a fishbowl. Because why not??

I've been coming here since 1999 & nothing has changed. The food is great, the outdoor seating is casual & the perfect place to enjoy something to eat & drink after a hike or bike.

I love a good flame-kissed burger, and here is where you can get a good one! Very casual atmosphere, friendly vibes, recommend everyone eathere at least once while in Ketchum.

This place is like stepping into a time capsule from the 70s. I was told everything was original except for the fryer! Even the guy next to me was watching a football game from the 70s on his iPad. Can’t even make that up. Burger was delicious and the 32 oz beer schooners are definitely a novelty. Pricing is fair and if you sit at the bar you can chat it up with the cooks and bartender. Everyone was full of local tips.

I had the pulled pork special and it was as mid as could get. Bland mashed meat on a less than exciting bun. The shoestring fries are the only thing that kept this from getting 2 stars. The hamburger my wife got was undercooked, pink and cold in the inside.

Really cool little place. Great customer service, everyone is fun. They just call out your name for your order so keep an ear out. Burgers are good plenty good size. Drinks are big seriously. Fries are fries. But it's a great place to get some good with friends or family.
