Gourmet Burger Kitchen (GBK)

Delicious burgers in a relaxed environment. Almost missed the entrance (it's right next to the clink). Clean and comfortable but a little worn around the edges in places. Would recommend the cloudy lemonade with refills.  If you want skinny fries - be aware that they are REALLY skinny  😀!

Well we haven’t been for super long time in Gourmet Burger.  But it’s changed since! I was super surprised when we order skinny chips and come super small!!Is funny set up;-(. You need to go to bar order food?! Is not bar  not restaurant:?

Had a lunch here whilst browsing London one Saturday. Good choice in the menu and staff were friendly enough, We were first customers of the day.
The food was a mixed bag. My wife and I shared two burgers, one was delicious and one was really average verging on poor. The great  burger was their standard with bacon and the poor burger was a fancy one with truffle oil (it really didn't taste of much and wasn't worth the money). The original was immense and I would eat again in a heartbeat. We ordered sides which were the sprouts (ok) cheese truffle fries (not worth it at all) and onion rings (tasteless and really greasey). 
Food was hot and came out promptly and we were in and out within 20-30 mins without feeling rushed.

I'm so jealous of anybody that lives near a gbk branch. They are the best burgers ever and I wish I could go to one every week.

I like GBK, and although this one is part of a busy mall, inside it's quite cosy and has a different vibe

Institute of Islamic Jurisprudence has certified this establishment as offering one or more halal options.  Per April 10, 2011 GBK website, the chicken used for burgers is Halal and is cooked in 100% rapeseed oil in a fryer specified for chicken only, however the grilled chicken used for salads and kebobs are cooked on the same grill as the bacon. The beef, lamb, and venison are not Halal. GBK does not offer halal Grilled Chicken as an option.
