I am pretty sure that these guys know what they do well and stick to it. I had a giant hamburger and fries. Good meat, cooked to order so it was nice and hot. These guys take business seriously, but it was not rude or unfriendly - just matter-of-fact. This seemed to help keep things moving, and as I was anxious to get my food quickly it worked for me.
The fries were fine - most importantly they were hot and fresh. They were a little overcooked for my taste, but they were definitely crispy and I know many people who prefer them this way. The burger and toppings were good, and big, and filling. I would get this again if I were in the neighborhood and had a few minutes to spare for lunch.
This was definitely 3 1/2 stars, a rating Yelp does not allow.
