One of the best burgers in Grand Rapids. Get the Fat Boy or Super Fat Boy, extra olives

The burger was pretty good! Cash or check only! P.S. don't squeeze the ketchup bottle too hard, the top will explode off the bottle. Funniest dinner ever.

Fat Boys is the BEST! Good staff , yummy breakfast , awesome burgers ! Thank You to the new owner for cleaning that place up!

Great burgers . For breakfast , love the sausage slider

Just good food done right. Get the Fat Boy burger, shredded lettuce, olives ,and mayo ! Solid!

Just had one of the best bacon cheese burgers ever

Now on their (insert #) of owner, they have finally returned to fresh burgers . If they used organic beef they would become the toast of the fast casual restaurant scene. They should see HeffronFarms

Best place in the world! The ladies that work there are so sweet! Thank you!

Locally owned, great burgers and onion rings !

Excellent cheeseburgers & fries !!

Bring cash and a crash cart to restart your heart.

The onion rings are cracktastic!

Best sliders in gr

Great for take out

The new staff setup makes Fat Boy a neat little north end breakfast place.

Deffinetely gonna be back great food

The exorbitant fees charged by the credit card companies to offer this service was just too much -- it is not free. Rather than raise prices on our menu items, we chose to eliminate credit cards...

The onion rings are way underrated.

Great service and great food!

Sunday breakfast only served till 11am

Cash or check only. Thank goodness I had my checkbook on me!

Organic burgers my ass, still a very good Fat Boy Burger

As the owner of Fat Boy, I would like to respond to a couple of previous posts. First, Fat Boy serves its full breakfast menu until 11am. After 11am, we offer a limited breakfast all day...
