lunch rotation. but no way does it blow 180 out of the water. They are drastically different. If you haven't had 180 taco's Al Pastor (it's the friday special) you are missing out. The Holy Taco Al Pastor is legit authentic al pastor, cooked using the OG method, seasoned the OG way... 180 taco doesn't have a spit to cook their meat on, so they cook it in other ways, but that taco is really really really good. Not as authentic but really good.
There are really only two really good mexican options at 180. Achiote pork, and the Friday special mentioned above. The other mexican options range from good/not great to meh/not worth the price.
