My first visit to a GBK six years ago (on the trail of a really good burger) meant making a trip out to West Hampstead. Since then, upmarket burger joints have sprung up everywhere and despite the stiff competition, the GBK seems to maintain its high standards. The Bloomsbury branch, tucked down one of the walkways at the Brunswick Centre, is spacious and relaxed and lacking the frenzy of some of the other locations. The staff were welcoming and drinks arrived promptly. A ‘starter’ of breaded mushrooms was accompanied by a piquant garlic mayo dip. Everyone raved about their respective burgers – the meat was well seasoned, juicy and cooked to perfection, served in fresh buns with just the right amount of relish. The chips were piping hot and generous. My only irritation is how much all these places charge for extra bbq sauce/mayo etc. but with the current 2 for 1 offers, the meal was very reasonable. For a reliably good burger, the GBK is hard to beat.
