The KERB Market was born in Camden in late summer 2016 after the Camden Lock Market was redesigned. The successful market was then exported to other parts of London. One of the newest venues is in Kings Cross. In the middle of the biggest companies like Google and schools like Central Saint Martins, the employees and students go there to enjoy new exotic foods. The area is still full of nice places to eat, like Wasabi, Tortilla, Kimchee, Leon and Vinetoca but this market has the advantage of changing food trucks, so you can discover different items each day, like the coffee of Noble Coffe, a brownie from Batch Bakery or an authentic paella from Jamon Jamon. They also offer burgers, pizzas, tacos, juices and other sweet desserts.
Go there early as there is often a long queue. The prices are not that high as you only pay for the food. Nearby, there are some tables and chairs, as well as some benches. The nicest view is on the stairs next to the Canal, on the fake green grass. Also, the market is only there from Wednesday through Friday, from 12 til 2, so plan ahead.
The other markets are in Paddington, Gherkin, Canary Wharf, London Bridge and of course, Camden.
