A Denver classic. One of the two remaining burger joints from the car era. The griddled burgers satisfy everything you want with two sizes: tiny and massive. Get the large triple with cheese and skip the fries. It may be lunch and dinner, but oh so damn good!

Soooo good! We both ordered a small double burger with cheese, and onion rings. The patties are thin, but I would’ve still had plenty if I’d ordered a single. Regardless, the burger was excellent. Flavorful and filling, we got every topping on ours (lettuce, tomato, etc etc) and it was fantastic. What a great Denver find!

As good as I remember from "way back"! The buns are different, though not in a negative way (since the originals are no longer available). Overall, I'll pay the price for these over less tasty-same-priced "burgers" from the national chains any day!!!

Great classic fast food style burgers but they're as big as a plate. Thin patties so I suggest a double. Don't forget to try one of their many milkshake flavors.

I always get the same thing when I go here. Double meat and cheese with everything, add mayo. It can be hit or miss some days, depending on how busy they are. But even when something isn't up to par, it's still pretty damn good.So, even is the meat is slightly over cooked, or the bun is a tad stale, (only issues I've ever had) it's still a great burger. And those things can be over looked.

I had high expectations when I visited. This place came up as highly recommended by Google reviews. When I got my food I was a little disappointed. The hamburger bun was a different type of bread than the normal bun. It wasn't bad, just different. It just threw off the taste of the sandwich. There were ample amounts of dressings. Plenty of fresh lettuce, onions, tomatoes and pickles. The bun just ruined it for me. The fry's looked amazing. Golden brown and hot. They just weren't crispy or crunchy. And they weren't salted. Ask for salt. Also ask for condiments on your burger. If you don't ask you won't get them. I see by the reviews this place is a local favorite. Give it a try.

A delicious no-fuss diner burger spot! Super thin smash style patties and your traditional fixings. Affordable and tasty! The thick battered onion rings are also divine.

A nice big burger! The workers are good people and have a great attitude.

I've been going here for years never had a problem until today. I hope it's a one time deal cause this is a good place too eat.

Ive been here several times over the years and always love their milkshakes but today I didn’t love my burger or onion rings. Oh well, I’ll always be back
