I love this. Obviously there's not much variety in the gameplay, but the mood of this game is fantastic. I love that you can change the radio station. It reminded my a bit of Lo-Fi Player. Maybe you could add more interactive things that don't actually interact with the core gameloop like that? I think you could definitely build on this and get a great little game out of it. Something you play to just relax for a while. I'd like a bit more variety in what the customers order and what sort of "minigames" you need to do to make those orders, but I wouldn't add any pressure like so many of these types of games have. It feels right for this game to just take your time with each order and vibe.
