The NYC Foodie has been going strong on his mission seeking out the best burgers in town. A few weeks ago I stopped by (for the second time) Mark, on St. Marks, to consume not a burger, but a slider. The prices at Mark are unbelievable. A regular slider is just $2.00, add bacon for 75 cents more. Since I need to watch my figure I went with the double bacon slider for $5.00, which comes with cheese and onions. It is a wonderful slider and I highly recommend it! The fries ($3.00) are really good too.
