The way I would ask my friends if they want to have a drink is: "¿Te apetece tomar algo?" o "¿Tomamos algo?" "Bebida" does exist but I've never heard anyone referring to a drink as "bebida" in the oral context. If you're talking about alcoholic drinks, we usually refer to them as "copas" so you could also ask "¿Te apetece / quieres una copa?" or simply "¿Una copa?" Hope that helps a bit!

¿Quieres tomar algo? it refers to any drink. ¿Quieres algo de beber? it refers to any drink ¿Quieres un refresco? it refers to non alcoholic drink ¿Quieres una copa? it refers to an alcoholic drink ¿Quieres un café? it refers to any kind of cofee
