As of my last update, there isn't a specific "Planet Earth Bar & Restaurant" that is well-known globally. It's possible that a local establishment by that name might exist in a particular city or town. Since bars and restaurants often come and go and my information might be out of date, the best way to learn more about a specific "Planet Earth Bar & Restaurant" would be to search online for the most current information.

You can look it up on search engines or review sites like Yelp or TripAdvisor, which could provide the location, menu, customer reviews, hours of operation, and other details. Additionally, social media platforms could be useful to see if the restaurant has any presence there with more information or updates. If you have a specific location in mind, please provide that, and I can give you more directed information based on that.
