My corporate office is nearby and a co-worker was SUPER excited that there was a Mucho Burrito available for our lunch. As someone else noted, it's a similar concept to build-your-own burrito places we have in the US like Chipotle, Qdoba or Baja Fresh. (Except in the States, there is only one size - ginormous - because US peeps are all gluttonous)
Anyway, I like to defy convention so I ordered tacos at a burrito place. Actually, they were pretty decent. The carnitas meat was well seasoned and not fatty and the hot salsa was actually HOT. You can pick your toppings which is always nice.
Mucho Burrito claims to be "Toronto's Best Mexican". Who am I to argue with that claim?
