You can't judge a book by its cover – but you can judge a restaurant by its bathroom.
Health experts say you can tell how clean a restaurant's kitchen is by how the dining room looks.
If the dining room smells fresh and the carpet is clean, experts say the kitchen is probably clean too.
If it's a rated restaurant, and the rating sticker is 10 years old, chances are you may not want to eat there.
And you may want to check out the bathroom before you take a seat at your table. Because if the bathroom is disgusting, so is the kitchen.
