Sometimes the best food is to be found right under your nose. Hidden in plain sight. In the case of the queue that snakes out of Listo Burrito on Oxford Street at lunchtime (and on the day I dropped in, the queue was obstructing the entrance to Banh Mi Cô Ba next door) this is quite literally the case.
Everyone in that queue had the possibility of a better lunch right under their noses. The burritos at Listo Burrito are decent.
I had one to check what the fuss was about, and it was totally fine. Nothing wrong with it at all.
