My husband and I went two days in the row, since we had business to attend in the area.
Very pleasant experience overall. I had the little cheeseburger one day and the next the hot dog with all the trimmings. Good quality meat in the burger and the veggies in the bun were fresh and crisp. The wiener in the hot dog was a little salty for me, but I guess that's how they make them these days. I like the fact that they cut the wiener lengthwise in half and grill it to give it some flavour.
Best for me: The french fries. They are so yummy, hand cut, perfectly fried not over-salted. They even tell you where the specific batch came from ( ours was from Vauxhall, Alberta golden wonder). The amount they serve is a bit insane (in a good way). The first day we ordered the large to share and there were so many in the bag that we couldn't finish them and brought the doggy bag home. That large portion is easily enough for 4 people. The second day we shared the small size and that was more than enough for us
The staff is very friendly and professional. Bathroom tidy and clean. Decor very appropriate. The music selection is awesome, just the right loudness to make it fun but able to converse with your friends and family. Great selection of 70s classic rock, which I think is very cool. Some of the other restaurants I have been to lately play music far too loud and the kind of teen pop that makes me want to scream or get out and eat in the car.
Overall Five Guys Burgers and Fries is a recommendable place to eat.
