More of a 3.5 + but not quite yet at 4.
For the price of 3.50 flat fee for a decently sized churro, Mr. Chu offered a soft but slightly dense churro. After eating the whole thing I found myself wanting to cleanse my palate. The inside was nice and soft and the outside fried to crisp, but it was denser than usual to my liking. Might be because of how the centre was not hollowed out. There was a lot of cinnamon sugar covering the churro so maybe that also contributed to the need for water.
Overall would go back. Not sure how it'll be with the toppings and ice cream but worth a try!
