I had a great experience at Chimichanga, so I'm a bit confused with the bad reviews on yelp.
My Mangorita (mango margarita) was the right amount of sweet and tang - I would come back for the margaritas alone. The food was just as good; the flautas we ordered as appetizers were crispy, flavourful and fresh. The tacos carnitas, soft taco shells filed with pulled pork, were well complemented by the guacamole and hot sauces on the side.
There were several people dining in the restaurant, some lively groups as well as a few subdued couples, presumably on date night. The staff was friendly and I felt we were well-attended to.
