This was a fantastic find off the beaten path in Vegas. While I'll tend to agree that the area seemed a little shady, it is in a heavily trafficked section of Vegas so I wouldn't be too worried about it.
As for the arepas, they were delicious. We went with the carne mechada and the reina pepiada. Both were filled to the brim with meat and other delicious fillings. I also tried an interesting Venezuelan soda drink that reminded me of a fruity cream soda.
The food came out quick and the service was friendly. I would definitely return.
