I moved to the Triangle from the San Fran Bay area about 2 1/2 yrs. ago and really missed my favorite taqueria, I couldn't find any Mexican in the area that compared until I tried Las Margaritas. My favorite thing to get is the carne asada tacos, I recommend them highly. Also, try to get a meal with the salad bar so you can get a piling heap of their pico de gallo - AWESOME!! The margaritas are good, my husband just had one there about the size of his head, he was very happy while I drove him home. Above all, the staff is very friendly and I've never had to wait to get a table or wait long for them to bring the bill (my biggest pet peave - waiting to leave!).
Pros: Great Mexican food, wonderful staff
Cons: Lunch can be a little pricey
