Why so cheap? The burger seems to embrace more proletarian affordability by keeping cost down with black truffle mayo. Also fancy is the use of curly endive. The rest of the burger is pretty standard with an Angus beef patty, tomatoes, bacon, and cheese.
The description reads: "The exquisite aroma of the black truffle, otherwise know as "black diamond" forms a delectable combination with our extra thick and juicy Angus beef."
