Wahaca's Mexican Street Kitchen (the silver van thing) in Canada Square Park will be giving away FREE burritos from 12-3pm today.
There will be a live Mariachi band to entertain Wharfers in the queue.
And expect it to be a big one – last time this happened it was mobbed.
For those keen to continue the party there will be a party tonight at Wahaca Soho's Azulito Bar from 7pm
