Shake Shack is delish, but none are near me. Smash burger was alright, there's one at newark airport terminal C. I liked the fries. Five guys is good all around, but not as good as Shake Shack. All are better than Burger King or Wendys and all cost more too.
There's a Red Robin near work that I went to once, it was good but didn't blow me away. Was also more expensive than all of the above, likely because it was a sit down service restaurant and bar.
