Good Mexican Near Andingmen

I've been here twice now and so far tried their fajita steak burrito, shrimp tacos, beef enchilada, and roasted chili's, all were pretty solid and tasted fresh. Main courses are around 40-60rmb. Time from ordering until it arrived was about 20 minutes. Good Wi-fi. My only complaint is the place is so small and the bathroom on the lower level is too close to the entrance and seating, it can give the restaurant a foul smell when you enter. Despite that, it's the best Mexican food I've had in Beijing so far.
