Los Tacos No. 1 is arguably one of the best taco restaurants in NYC! They are as authentic as you get when it comes to Mexican street tacos in New York City. There are 2 locations in Manhattan, both typically with long line but great service. The Chelsea Market location does not offer an area to eat so be prepared to walk and eat. They have a simple but efficient menu and their signature taco is the carne asada but everything is good! This restaurant will not disappoint you.
