Pancho's is honestly some of the best churros ever. I've been a couple times but after they were listed as one of the best churros in the city (among other places) by BlogTo, my partner wanted to go on a churro spree. So this was our first destination. The churros are fresh and the service is so friendly. There's usually always a little bit of a line, but the service is fast and efficient and the wait time is not long at all. I believe it's $1.50 for a single churro, $4 for 5 churros, and $13 for 12 churros. In my opinion the dulce de leche and chocolate are the best churro fillings but you can get it plain or with strawberry filling (and maybe a couple others).
It can be a bit messy to eat but it's perfect for a cool weather snack/dessert.
My one issue is that this place is cash only and I never carry cash (so it's quite inconvenient for someone like me). However, if I know I'm going to be in the area before hand, I try to keep some change on me :P
