Found hair in my burger. While that is not completely horrible, I was put off by another thing I saw in the restaurant. They had red buckets of Sanitizer sitting on the food preparation counter. While I like to see a clean restaurant, I don't think keeping a bucket full of cleaners within a couple inches of the food preparation area is wise. Also the staff was spraying window cleaner on fixtures they were removed for cleaning. This again is a nice thing to see, but not when the overspray was going straight into the food.
Maybe a one time bad experience, but it just looked like some serious lack of supervision of the staff.
