New Burrito place in Reading & Oxford??!!

I was in Reading yesterday and noticed there is a new burrito/taco place openeing soon, behind the Oracle, next to Krispy Kreme. There was no menu up yet, only their shop sign but i think it MIGHT be a Rubios type place. Anyway it's called The Mission. I found them on Twitter, apparently they have a place open in Oxford already - anyone been there??
