Taco's El Gordo is worth the wait. Sure, you have to stand in the line for the type of meat you want and sometimes that can be a while or even make you wait outside depending on the time of day.
I really enjoy the Al Pastor they have and usually get it on a plate of french fries. The Carne Asada is also delicious and the way they make their tacos is so good. You can request flour or corn but sometimes they don't ask.
Overall it's a really good spot for Mexican tacos or meat over fries. I travel over 20 miles each way when I'm craving Tacos El Gordo and I'm always happy I did.
