I just had my first 5 Guys burger at LGA Central Terminal.

I thought the cheeseburger was the best I have ever eaten. The fries left a bit to be desired. I will certainly try one closer to home and see how the fries are there.

UPDATE:

I took my DW to the one in Nanuet, NY last night.
She made a funny face when she bit into her large hamburger. I had the samll cheeseburger and didn't understand what the problem was with her burger until I took a bite. Two patties was just WAY too much meat. She took a bite of mine and loved it. She also didn't order mustard on her's, which she regretted.

The fries were much better than those at LGA.^
