Mexican food seems like one of the forbidden cuisines when it comes to peanut and tree nut allergy. Even though nuts aren't readily apparent in most of the dishes, they can be hidden in sauces, like my favourite, mole. Quesada whips up tasty fresh burritos made to order, and according to staff at the King Street location, there are no peanuts or nuts used in any of the offerings. With three locations around downtown Toronto, it's a great option for allergy sufferers with a hankering for Mexican.
Always do your own research and ask your own questions before ordering food.
