"Burgers and hotdogs don't get more delicious than at MEATmarket, part of the Meatliquor brand. Upstairs in the market at Covent Garden, you can get what is without a doubt the most delicious, meatiest and flavorful 'dog in the city, and wash it down with a boozy shake (my favorite is the vodka, Kahlua and vanilla one). The burgers are fantastic too, so rich and meaty and dripping in greasy yumminess that I've never yet eaten a whole one to myself. The queue moves relatively fast, and the "classified ad" signs will keep you amused while you wait."
