The Best Burger in London

When we say we have the best burgers in London, we mean it. Right down to the texture and flavour. We’ve made numerous trips to the United States, including Richmond, Virginia, the Mekka of burgers in the United States, collecting the best-kept burger secrets and tips. We have replicated the flavours and made them even better with our family recipes.

Phat Buns Burgers has a unique selection of mouthwatering, dripping juices and flavour burgers, including the spicy buffalo burger, Phat American, Phat Chick, Double Phat Chick and Classic Phat Chick burgers. For burger connoisseurs looking for that unique experience, you can build your own burger using our four types of buns, three types of smashed patties and ten condiments. The variety of burgers you can make from this selection is unlimited, so go all out, create and tease your tastebuds. 

What Makes Our Burgers

The greatest ingredient at Phat Buns is passion. We are passionate about giving you the best burger experience in London. We also source the best and freshest ingredients that contribute to the flavour profile of our burgers.

Some of the common ingredients you will find in our burgers include:

  • American cheese
  • Gherkin
  • Tomato
  • Chicken
  • Selected sauces
  • Lettuce
  • Blended beef
  • Pulled rib

The combination of these ingredients varies depending on the type of signature burger you choose or the build-up burger you create. Each ingredient goes through intricate preparation, including a 12-hour BBQ for the pulled rib to bring that American touch to our burgers.
