I found El Sabroso after helping a friend move things into a Midtown showroom. We took turns bringing boxes into the freight entrance of 265 37th Street. In the loading dock, where there should have been freight elevators, there was a lunch counter instead, with six stools, one table, and a glossy red menu with the words "El Sabroso Restaurant" at the top.
Our Tip Tiny lunch counter in a midtown loading dock serving breakfast and lunch. Hunks of braised chicken and roast pork are great.
