I cannot say enough good things about our Mile End Walking Food Tour. I was hesitant at first to get tickets because they were a little pricey but it was well worth the money and it was by far the best part of our trip to Montreal! Justin was our tour guide and he was excellent! He not only was very knowledgable about the food but also gave us a lot of interesting info about the area itself. We went to 6 different food spots and the Rialto theater. It was the perfect way to explore the city while having lots of delicious food! We had a pleasant variety of sweet and savory options and they were very accommodating of any food allergies/sensitivities. They apparently do some different stops during the winter time so I think we'll have to come back and try a new round of restaurants!
UPDATE 8/20/17 - I returned to Montreal again this summer and I was about to sign up to do the same tour because I liked it so much and then I found on their website that they do tours of other areas as well! Needless to say I was super excited and signed up for the Plateau & The Main tour. It did not disappoint! Our guide Christian was phenomenal and used to live in the area, so he had a lot of good insight. He also told us that to be a tour guide, they have to do 8 months of training so they know all the important history and interesting facts of Montreal so you know you're getting good info! Just cannot say enough good things about this tour, it's an amazing way to experience the city!
