They are located on almost every major planet and are often also a center of criminal activity such as smuggling and spice trading. Cantinas are typically located on smuggler-affiliated planets, such as Faendra or Delica.
In some cantinas, dancers are brought in to perform on stages. Musicians are also popular entertainment. The main attractions, however, are the beverages and the opportunity to meet friends or business associates (illicit or otherwise.)
Some cantinas, such as the Illildor Une on Sinosa, are designed only for aliens to inhabit, because the air consists of fumes that are similar to the ones on their homeworlds. These fumes are, however, poisonous to most other species.
