I'm the opposite. I love five guys burgers but hate their fries. Though, I've become somewhat anti-fry these days.
I'm with you on that about the fries, they are not good for healthy eating. I didn't really like the garlic fries at Burgerocity but only because I thought they were over cooked, but I don't really like crispy fries but a lot of people do so that's probably just me.
My wife and I went to Burgerocity yesterday and this time I tried the sweet potato fries, those were excellent, much better then the fries IMO (and healthier). If they cut their fries the same way they cut the sweet potatoes I would like them a lot more. Great tasting fries are hard to come by.
I will say this, the fries at Five Guys were really good because 1) they're fresh locally grown potatoes but the biggest reason is 2) they cook their fries in peanut oil which IMO makes a huge difference in flavor.
