Tacos Los Guachi's

I ordered the tacos dorados carne asada. It came with four and it’s topped with lettuce, tomato, 2 slices of avocado and some cheese. I’m enjoying my taco all good with the first one. Onto the next taco … I bite and get the fat … I’m immediately disgusted. I did call the restaurant and the one I initially spoke with said she can’t do the credit back but to wait and someone will call me back. The second person called me back and said she needed proof of what I was referring to. She asked if it had that why couldn’t I eat it. Well excuse you I am currently pregnant I’m more sensitive to what I eat that alone made me nauseous. Secondly this was ordered on my lunch break … I cannot simply leave work again to fix the meal I paid for. This is unacceptable! I shouldn’t have to pick apart the taco to separate the fat to then eat the meat. I should be able to bite into the taco without a worry. The photo there shows what was inside the remaining 3 tacos. Go somewhere else. I’ve eaten tacos dorados plenty of times at other places and never NEVER do I get fat in my food. As matter of fact I don’t even get the meat fat in any other meals that I order at other places. Unacceptable!
