This place has no dine at location options but even that won't stop them from making tasty food. One of the last placed to make a truly large hamburger

One of the best burgers I’ve ever had. The size is amazing for the cost. I can’t wait to come back and try a shake!

Usually their food is bomb ordered a burger today it was done in less than 5 minutes they weren't busy after I drove off I've been into it and bad lettuce open the burger and it's brown lettuce like it's been sitting there for a while highly disappointed Federal is too busy to try and go back. Milkshake was good but all together it was not worth 15 bucks. Food is better whenever they are busy so is service

Pretty good! My go-to is the double steak with cheese. Huge burgers. Definitely plan on not doing anything after eating one. Friendly staff.

This place usually takes cares of their costumers really good. This was my 3rd time coming here but unfortunately I think it’ll be my last. Costumer service is one of the worst I’ve had. I stood in front of the ordering window and I was ignored for around 10min before the cashier took my order. With a very blank stare she asked what I needed help with, like if I was going to beg for the food or something I come to spend my money and the attitude is just terrible. I understand they’re busy but a little courtesy goes a long way just letting the costumer know you’re going to take a while goes a long way. Good has also gone downhill the patty was small and lacked flavor over all and the fries had very little seasoning. I visited this place Monday 16 June 2025 at 7:00pm and my last visit

Best burgers in west Denver

After a couple try’s we have to say this place is over priced and slow AF - you’re cooking fry burgers that take a minute to cook. After two times we waited 30 mins for one order and the second time we waited over 13 mins for a single burger both times. For the price you could do Park Burger or Jim’s burger Haven and save yourself the grief or wasting your whole lunch break waiting for food

Burgers close, but are not truly Grandpas! The buns are absolutely gross! Change the name because it is not the same! Thx native of Colorado here who was a customer for 40 years. And way overpriced

Lol idk what’s all this hype about but this place is absolutely disgusting and filthy! $25 for 2 burgers that barely have any meat! And it smelled so bad that we had to throw it away!! It’s dry, veggies are literally rotten, this is definitely the WORST burger I’ve ever had! Please avoid this dirty place.

I really liked this smash burger. I ordered the large double with cheese and bacon...this thing is LARGE. See pic. I also ordered onion rings which were good and a Jalapeno Shake. This shake was vanilla with spice of jalapeno. No chunks. It was good and interesting, but I would order an Oreo shake or one of my usuals next time. The lady I ordered from was very nice too! I'll be back next time I'm in town.
