El Pastor (London)

El Pastor delivers London's most authentic al pastor taco, using a trompo stacked with pork marinated for 24 hours and shaved directly into tortillas. The Hart brothers replicated Mexico City's street cart technique with a secret spice blend that includes achiote and pineapple, serving over 800 tacos daily at their Borough Market taquería. In taste tests, their al pastor outperforms #10 Cosme's duck carnitas in both juiciness and traditional flavor, scoring 4.7 stars from 1,200 Yelp reviews. Each taco costs just £4.50, making it cheaper than the average London taquería by 15%.
