We were celebrating a birthday in the family. Our youngest son requested Mexican. We had hoped to eat at the restaurant, but it is too small to accommodate a party of 6. So we had takeout, and had the food at home. The food was delicious! I had a beef burrito. All of the many other dishes were great. I will definitely ngo back to Si Sinor!

Tacos were a bit on the cold side, but they were still delicious. Service was alright, not quick but they were friendly and brought the food to the table. It is om Rideau st, so you always have all sorts of people coming in who affect the atmosphere.

Absolutely incredible! This Mexican street food spot is a hidden gem. The flavors are bold, fresh, and authentic every bite feels like you’re eating right in the heart of Mexico. The tacos were perfectly seasoned, the tortillas soft and homemade, and the salsas had just the right kick. The staff were super friendly and welcoming, and the atmosphere was vibrant and full of good energy. You can taste the love and passion in every dish. Definitely my new go-to for real Mexican...
