After a day at Tikal my fiancé and I were starving. We saw the menu and location and thought this would be a safe bet. I saw they wrote on the menu that all of their vegetables were washed with purified water. This put our minds at ease. It took them a while to take our order. They were not very busy. I ordered a Hamburger and my fiancé ordered a salad. By the time I got the hamburger, I was beyond hungry. I took a bite and noticed the bread tasted like it was stale and had been toasted to hide it. Upon closer inspection of the bun, I noticed chunks had been taken off the bread and there were little blue/green spots of mold on the rest of the bread. They had obviously intentionally given me moldy bread. I spit it out and left. This experience made me paranoid about eating at these restaurants in the off season. I would have paid anything to have a descent clean meal. Ended up eating at Burger King that day, although the best meal I had on our visit was The Mayan Cafe.
