Sí Señor Mexican Street Food

About Sí Señor Mexican Street Food

Sí Señor Mexican Street Food brings authentic Mexico City flavors to Ottawa, earning recognition as "Canada's Best Tacos" by the Jarritos Cross Canada Taco Tour and "Best in the City – Mexican" by Restaurant Guru. Owner Hugo Crespo imports recipes directly from Mexico City, creating street food that captures genuine Mexican culinary traditions.

The signature QuesaBirrias exemplify Sí Señor's approach: slow-cooked beef in house birria sauce, drizzled with rich consommé that transforms simple tacos into memorable experience. This dish alone justifies the awards and loyal following. Beyond QuesaBirrias, the menu spans authentic street food from tacos and burritos to tortas and quesadillas.

Authenticity extends beyond recipes to preparation methods and ingredients. The kitchen respects traditional techniques while maintaining accessibility for Ottawa diners unfamiliar with street food culture. Generous portions and reasonable prices reflect street food values—satisfying, flavorful, affordable.

With two locations on Rideau Street and Preston Street, Sí Señor makes award-winning tacos accessible across the city. The casual atmosphere encourages quick meals or leisurely dining, accommodating various occasions from lunch breaks to weekend gatherings.
