Two of London's best are getting together for this mighty burger - on sale for March only.
An American/Mexican hybrid called The Wall (you can guess what that's based on), it's an aged beef patty, brisket birria, American cheese, burnt morita chile, sesame seed salsa, jalapeño, lemon, onion. All that plus for each burger sold they'll be donating £1 to Save the Children charity for their U.S border crisis work.
The Wall will be on sale from all Lucky Chips (Dalston, Camden, Islington) for the whole of March 2017. We'd like it to be March now, please.
