Everything to say has already been said on here so I will just throw in my 2 cents. My wife and I went here for lunch on Sunday afternoon. We both had a burger and shared a regular regular fry. First off, the fries are excellent and a regular one is enough for 4 people. I would like to try the cajun ones in the future though just to see if they are any good. The burger was very good as well. I think they are a bit pricey for what you get but I'm still a fan. I guess all those free toppings make up for the high cost of the burger a little bit. Also, the patties are a bit thinner than I expected but were still pretty juicy and flavorful.
Our whole experience was a positive one and the cashier was very friendly and helpful.
As far as Mill Ave. is concerned, this is probably the best burger on the block because I really dislike FatBurger's burger.
