it only cost me £15 for both of us, and we left after about 10 minutes fairly satisfied. i couldn't tell you if changos burrito is better or worse than barburrito, they seemed about the same to me.
with mexican inspired places popping up all over town, and with lucha libre opening shortly, it seems changos have appeared at just the right time. it's always interesting when somewhere is so busy they have a queue at lunch time, in this case i think it's the right product at the right price and most importantly the right location.
so, is it worth queuing for? no, not for me it isn't.
but it is a fairly decent lunch and a much better bet than a supermarket pre-packaged overly chilled bland sandwich. and it is a great little business, so good luck to them i say, though it doesn't look like they'll need it.
