    This is a good place to go and mix up your burger routine. It has a "throw-back-cali-vibe" and an appropriately experienced staff.

    I suggest getting a large double, "extra everything", add mayo, and bacon. The patties are thin so skipping one might leave your burger a bit dry.

    Meals comes hot in a paper bag to-go because there isn't really seating.

    Support your local grandpa, folks!

    Solid burger joint. Got to at least do a double if you go large. The large single is ridiculous, as it is a thin patty stretched inside a huge bun. Small triple or large double is solid choice.

    Fries are not terrible.

    Drink situation is wanting.

    A disappointment. I.was expecting a really good burger. I didn't realize that you have to double the patty. Way too much bun and not enough meat. The fries were kind of mushy also. The only good item there was the onion rings. It is sad when McDonald's and Burger King puts out better burgers!.

    Yummm! This place is so amazing, I visited twice in 4 days while visiting Denver. I'm so thankful to the internet for leading me to Grandpa's Burger Haven.

    The fresh, thin burger patty and smooth, perfect bun are the base for what is one of the best burgers I've had in my life! Definitely up there with all the classics - In N' Out, Five Guys, Shake Shack--Grandpa's Burger Haven can truly hold its own.

    Their onion rings are INCREDIBLE! They're huge, have the perfect amount of crunchy batter, and feel like a meal on their own. I loved their fries, and the fact that they included salt packets for us to salt at our own discretion.

    We did end up eating in our car since there's nowhere to sit, but that was half the fun. If you're lucky enough to live in the area, you should DEFINITELY try them out! I know I'll be back next time in town.

    I was very happy with the double cheese burger and the chicken nuggets were the best I ever had.  The service was fast and friendly.
