The burger is nice, also huge (non-small burgers come with two patties!). Go for the Bacon-CB, the bacon is super crispy & tasty! Also try the milkshake — the strawberry milkshake was superb!
I tried getting into Five guys for 6 months in NYC but was always crowded. After so much wait, I was really disappointed in the burger, still better than Mac Donald's but less than GBK.
