After transplanting from San Diego to Las Vegas, I struggled to find comparable Mexican food. Finally, I found Sin Fronteras. I ordered from Yelp and the owner delivered the food himself, he called first as they were out of one of the items to ensure I received something similar. When he arrived he was SO kind, he found out we recently relocated and was quick to give recommendations and stand in the driveway to chat. The food was the closest I have tasted to San Diego since. Great chimichangas and churros and they are so quick! We haven't ordered from another Mexican food shop since. I highly recommend this place.
