Selling off food

My partner and I visited Mochachos in Trade Route mall on the 10th April. The 1st thing I noticed was an elderly man (seemed like the owner) with folded arms staring at the cash register. After ordering to sit-in a strong horrible smell was around the dining area. Over looking this as we continued to wait for the meal. The chimichanga was more of a small cheese pie than chicken and the reason i noticed this so quickly was because i had ordered the same meal 2 days ago from another branch. My partner eat the top layer of the chicken and then felt nauseous she then proceeded to smell the chicken which clearly was off and smelt terrible. The manager was kind enough to offer another meal after she had smelt the chicken however we declined. The elderly man watched but had no decency to approach us and find out what the problem was. I should of asked for a refund but we just needed to get out of that appalling restaurant. It seems that the owners are more concerned with making money and have no regard for customers or proper hygiene practice. Absolutely pathetic service from this particular Mochachos
