Wow, this is the first time I've had colombian food so I cannot speak for it's authenticity but the food here is amazing. I really wish it wasn't so far for me as I would definitely be a regular there.
The owner is really friendly, being our first time eating colombian food, he took the time to walk us through the menu and give us recommendations.
I especially like the tripe soup. Very very flavourful! A must try, you can get this in a smaller sized to go with a main (if you want to try more).
Remember that there is parking behind the restaurant.
