Mr. Chu is a small food cart outside the convenience store around Yonge and Finch. It's really great if you're craving something sweet and Instagram worthy :) The wait is a little long, but it's understandable and the guy that was working when I ordered was really nice and gave me paper bags to carry the churros in (I ordered four for my family and I).
I ordered the original churros and then two specialty churros, chocolate almond and sprinkles. They are really delicious, but really sweet for my taste but my family absolutely loved them, so.... Overall a nice dessert/treat :)
