The Mellow Mushroom pizzeria has closed at CityPlace.
A listing for a West Palm Beach location no longer appears on the restaurant chain's website.
A call to the store revealed the following message: "The mailbox number that you are trying to reach is not in service, goodbye."
An employee who contacted WPTV says the store closed Monday with no warning to the staff. The person provided WPTV with the message below that was addressed to ALL STAFF.
The restaurant opened in January of 2013 and, in addition to the food, was known for its unusual decor.
