The Railroader Burger from Black Box Fix is probably one of the most amazing burgers I have ever had. The sweet/savory-ness of the onion jam combined with the flavors of the smoked gouda cheese make an amazing burger. I would highly recommend, and I don't even like mushrooms, but you can't even taste them.
However, quite let down by the fries that come with the burger. They tend to be quite soggy, and the cheese seems to just be thrown on cold. Overall the seasoning seems lacking, which is quite disappointing when you compare it with the burger. They are a little better when eaten fresh, but since I usually order to-go, by the time I eat them they are cold and I won't finish them.
Also, not a huge fan of the Chicken Philly. I personally found it pretty dry, which makes it boring and difficult to eat after the first few bites.
But hey, four stars because I will definitely be back for that burger again.
