I went to Five Guys in South Common mall a few years back and hated it. Fries were bland, burger was plain and meat wasn't fresh or hot. Maybe it's because they just opened and were working out the kinks, but this experience here was much better.
Fries were crispy, greasy and salty - so they were great. Cheeseburger had fresh ground beef and really good "bad cheese".
Only thing I don't like is that they don't have combos, so kind of pricey.
