We went here maybe a few weeks after they opened. There was only one other couple there when we went, which is surprising for a Friday night.
We got the loaded nachos and the poblano tacos (which I wouldn't normally get, but they were the only vegetarian option). The nachos were alright, but they were more chips than anything else. Maybe about 60% of the chips were bare. We didn't like the tacos at all. It was just the poblano peppers, which weren't cooked properly, and a few other minor toppings. The sauce tasted good though.
I would probably wait a year or two and try this place again to see if they've improved, but it's definitely not on my list of go-to Mexican restaurants in Mississauga.
