I used to go here when I lived in Charlotte the First time. I recently moved back so we returned to las margaritas hoping it was as good as I remembered it. It was better! The prices are reasonable and the portions are pretty large (def can take half for lunch the next day). I feel like it's def one of the more authentic Mexican restaurants in the area. No nasty velveeta like some other places in the area. My family's Mexican and when I took my parents here they both approved. Try it out!
Ps- the carne asada is awesome!
