Thank you Melissa! just moved to the neighborhood and first thing i always do is find the best authentic local mexican dive to make my new go-to joint.  tried tacos jaliscos first but they are temporarily closed for some issue with their lease so, based on your review, i gave AMP a try and it was great!  this isn't just one of those places that smothers a messy blob of cheap meat in cheese and sauce, they have a full on legit butcher in the back corner (which you can buy from) so you know everything is fresh, authentic and made to order.  i got the steak gordita as you suggested, and a chicken taco, delicious, can't wait to go back.  I only subtracted a star because while I was browsing the groceries i grabbed a bottle of ketchup and it had an expiration date of June 2011, and currently it's March 2012, so i'll stick to Fry's for my grocery needs but will definitely come back here for the food.
