OK. I get it. This strata of "burger joint" is highly personal and people have their "love it" and "leave it" and the debate rages. For me, Five Guys is a "leave it."
The best item is the french fries. Good flavor. Insane quantity. And, most importantly, they stayed hot for the entire time it took me to eat everything else. This is not something all burger places can brag about. I will add, having eaten Five Guys occasionally over the years, that the quality of the fries is dependent upon the person making them and how careful they are to not over-salt them!
The chocolate malt tasted pretty good and is priced competitively. Not what you'd get from a good ice cream parlor, but also priced less.
The burger itself? I had it "all in." The bun fell apart almost instantly so I was scooping up bits off the foil with my fingers. The add-ins were only OK. Not the quality of ingredients from another - been around since the 1940's - burger joint out of CA.
$15 pre-tax for a "little" cheeseburger, "little fries" and a shake. That puts this meal price competitive with sit down restaurants. And, the sit down restaurants burger is going to be much bigger. The price for the "little" cheese burger at just under $6 is way too high for the quantity and the quality. For this price, it does not add up. Pass.
