Noticed the dining area in bad need of maintenance. Ordered a #9: crispy chicken sandwich, with small fry and small soda ("Sprite"). At first bite, I noticed the sandwich overly moist and extra hot (temperature). I inspected inside the sandwich to find mayo, lettace, chicken and an extra liquid which was yellow-ish in color. I immediately stopped eating and left the restaurant for something to drink (the soda was NOT a Sprite or any brand I was familiar with). 10 minutes later, I felt nauseaous and continued to feel nauseaous after having a bottled water.
