I had my very first Portuguese chicken sandwich at Coco Rico and really enjoyed it. The chicken was juicy and I had never eaten anything like it before. Although I asked for it spicy, I didn't taste much heat, however, it tasted delicious all the same. I personally like it best of the few I've had in the city.
I came in just before 9pm on a Wednesday night so there was no line. The sandwich itself came to about $6. It might be a little small if you are feeling quite hungry though, so make sure to add the sides for a "full" meal!
