It’s almost criminal how much they charge for a burger and fries. The worst part is the quantity of fries they give you has dramatically declined, yet they steadily raise the prices. $30 dollars for 2 burgers and a little (which actually is little now) fry is absurd. At least years ago they actually filled your bag with fries.

If you’re like me and love burgers but shudder at the thought of paying more than $20 per person for a meal without getting something more substantial, then Five Guys in O’Fallon might be a great option for you. I recently visited this location and had a great experience. The quality was good and the service was great. I ordered a double cheeseburger with all the trimmings and it was timely and delicious. The fries were also great, and the amount made me do a double take. I have to admit my concern that not everyone has had a great experience at this location. Some customers have found that the food was mediocre and lacked flavor or seasoning. But hey, you never know until you try it yourself! Overall, I would recommend giving Five Guys a try if you’re looking for a delicious burger.

I mean, its a burger and fries from a well known place. I do enjoy the attention the guy at the register gave when making sure we were satisfied with what we ordered. He made it a personable experience where some would have just taken the order to get it over with. Give that man a raise.

I love 5 Guys! This location is good too. The lady cleaning tables is good for conversation while you wait for your burgers. You might even see Darryl Strawberry. He orders here occasionally. My wife complains that it’s expensive but I’m willing to shell out some cash for the best burgers fries and shakes in town.

Decent burguers and fries Their free peanuts are delicious as well. A little on the pricy side. Paid $37 for 2 burguers and 1 large side of fries and ONE soda. Only 2 ppl eating. Imagine a family with kids eating there. $100+? Music was way too loud as well

Love Five Guys. I do. Their food is great. But they are a little pricey on their stuff. I understand they are high cause of the inflation going on in this country but the people that work at Five Guys are great. Keep up the good work

As soon as I entered the store this old lady named Jacquelyn S was staring us down. It was my first time there, and she didn’t even give us a chance to look at the menu. She had the nastiest attitude, and after i ordered, while I was waiting she was staring at us making us feel very uncomfortable. Also, the fries were very salty.
