People tend to check in during these times:
Delivers fantastic, fast, thin patties with a squishy bun, crisp lettuce, fresh tomatoes and special sauce reminiscent of In-N-Out. Low prices too! Winner of critics' choice for best burger joint.
Just good people making great burgers for a fair affordable price. A serious breath of fresh air ...ok a little fresh greasy air!
These simple, fresh, classic fast food-style burgers are some of the best in Williamsburg.
That burger was amazing. On par, if not better than, Shake Shack.
My prayers have been answered, they have veggie burgers now!
A little overhyped -- good burgers but not in the same class as Shake Shack
The best chili fries I've ever eaten.
This place just keeps getting better. Double cheeseburger and Cookies n Cream milk shake is my jam.
Best "non fancy" burgers in town. But I wish they had bacon as an addition.
Tasty burgers, but these people saying it's better than Shake Shack must be smoking crack. Either that or they haven't had a double shack at Madison Square in awhile.
The burger is identical to shake shack's but at a better price and without the ridiculous wait. score.
Good, cheap, no frills burgers.
A+ burgers and fries and shakes and staff and EVERYTHING. Super cheap and open late. Awesome addition to the neighborhood!
Pretty damn close to the burger of In-n-Out. Simplicity.
The cookie and cream shake is amazing.
Def worth it.
Better than shake shack.
Walked to Blue Collar/ burger joint, brand new. Goos eats, it's true cuz I only eat what I like to consume and to much ado, time to introduce BLUE COLLAR GOOD JOB to the burger joint crew.
Great Shake Shack-style burger in Williamsburg. Thumbs up!
I eat here so frequently that Blue Collar is definitely contributing to an ensuing heart attack. I have no problem with this. Perfect way to go out. Eat it all.
Awesome chili burgers. Go easy on the fries, they're large and best shared. Cookie dough shake or nothing.
Awesome burger & fries. Prefer this burger over Shake Shack any day. Staff is really friendly and there's never a wait. Also... The Peanut Butter Milkshake! MY GOD.
Double cheeseburger, fries, and shake. Die happy.

Awesome cheeseburger and cheese fries. So happy they deliver (30 min from phone call to door). Messed up on entire order but guy came back w the right one. Rad service.
The veggie burger tastes surprisingly like a greasy cheap beef burger. Not what I was in the mood for this time, but maybe if it's really late at night next time.
Double cheeseburger, that is all.
New York Magazine Cheap Eats issue calls the Flat Top Burger "an an unassuming, nicely proportioned, modestly accessorized old-fashioned burger with a fine texture & salty flavor that hits the spot."
TimeOut raves about their "In-N-Out" style burgers.
Great A/C on a hot a hot day! And free soda refills!
Double Cheeseburger. A burger and shake spot that walks the line between fast food and fancy on the patty scale. Fries are thin and extra-crispy, with a dusting of housemade seasoned salt.
Best double cheeseburger
Holy crap these burgers are amazing, think shake shake but bigger! Fries are so so though.
Put chili and cheese on those fries. So good!
French fries are awesome. Not very greasy at all. The burgers are very tasty as well!
Wish they'd turn on the heat we're freezing
Best burger in Brooklyn.
This place took forever to serve up some cold fries and sloppy burgers. I drank their milkshake, but they still get a big PASS.
Chocolate milk shake is so thick. Yummmm!
Good greasy burgers. I'd take Blue Collar over Shake Shack any day.
The peanut butter shake! Oh man! It's so good!
So glad to have this place up the block! Great food and staff!!
Buenas hamburguesas, buen precio, ambiente y decoracion sencillo, perfecto!
