GBK - Gourmet Burger Kitchen in City of London

Just had lunch, always quick and easy to order. Great burger as always and cooked to perfection.

This is the 5th GBK restaurant I have visited however the staff at St. Paul’s were the most helpful and friendly after having a small issue with the app (my fault) it seemed like they really enjoyed their job knew exactly how to help me! The restaurant was very clean restaurant and toilets aswel. best milkshakes and burgers in London. Loved it, I’ll be back for sure! Thanks GBK St. Paul’s. Well done to the managers.

Great burgers and fries. The Hei Hei salt (it is seasoned salt containing herbs and spices) on my fries seemed little different to ordinary salt. Simple salad was good, but not dressed, there was a squirt of vinaigrette on top, but the leaves had not been tossed in it, still tasted good though. Staff were friendly and welcoming. Relatively unusual in central London.

I must say I had burgers all around the world but never had one as good, you can tell the meat is so fresh ,the cheese was just perfect the bun was the best.. not sure what i liked the most. But overall all it was world best burger.Last I don't want to forget about the service 😕 so nice and friendly.The restaurant is so fresh and clean.I would challenge this burger with top Michelin star restaurants.I wish them all the best.Keep the good work..

Great burgers. Huge portions. View of Saint Paul's across the street. Vegan options on the burgers too and very tasty. Lucky to be here during a quiet hour. Great service and quality.

Food is good, burgers are yummy. Shakes are good too but I prefer them filled to the brim. If you can get vanilla right, rest of the food is bound to be good. A+

Nothing stands out vs other burger places, although still good quality burger. Comparable to five guys/shake shack/etc

Great burger! We went about 4.30 and there was almost no one there. The staff were friendly and we got our meals quite quickly

This is the fourth time I've received the wrong order from GBK St Paul's. Twice with uber eats and now twice with deliveroo. Really disappointed as GBK used to be my favourite burger spot but with this happening so many times it's hard to rely on type of service from them.

Got the classic beef in the £5.95 lunch deal (burger seems smaller than usual) along with a chocolate shake for £4.90. Was looked after by the friendly staff and there's a camaraderie between them. Hopefully will reopen again.
