I got a single and my boyfriend got the big double and it was HUGE he almost couldn't eat the whole thing. My single was good but it would have been better if I had less bun, or more meat I suppose. The toppings and bun were almost over powering, but it was well rounded enough that I would get it again, unless I had more of an appetite then I would go for 2 patties just not the big big one my dude got that was crazy, but he said it was delicious and filling so he had no complaints either. Very small dining inside if any, there are a few 2 seater tables along the windows, and a table or 2 outside to eat at but it seemed more like a place your order and go kind of place. Walk up and drive through ordering available.

Steak burger was delicious and fresh. Cooked perfectly! Fries were super fresh! Minimal wait. Staff was engaging and friendly. I've been here a bunch but today (9/22/25) was definitely the best I've had here. Thanks so much!
Highly recommend!

Really good burgers and American type food. The wings were surprisingly good. The large burger is huge. Food is fresh but it can get a little pricey I wish there was a combo deal.

Grandpa's Burger Haven with my brother. This place has been around for a long long time. They are famous for the big bun burger. This thing is huge, the patties are smashed and come with lettuce, pickle, onion, tomato. Fries are cut thick and were really good.

Large double with cheese with everything and a side of onion rings will set you free! (Might need a nap as well)

Ordered 2 burgers and 2 fries when they weren't busy. Took 45 minutes to get the food. They forgot 1 of the fries. Food was OK, nothing that was worth calling great.
