The bacon cheeseburger "all the way" is amazing. All toppings are free. And the soda machines have things like raspberry coke and a 100 other flavoured coke drinks.
Five Guys Harlow Water Gardens serves burgers and fries how they are meant to be. High-quality Scottish beef, hand cut fries and as many fresh toppings as you wish in any combination you'd like. You can also create your own flavoured shakes with a range of different mix-ins.
