I think today’s fast food restaurants are too noisy

So I suggest that your restaurant play some more soothing English songs, because I personally feel that when listening to Chinese songs, Everyone will naturally want to hear the lyrics clearly, so if you play English songs or songs in other languages, everyone will be more relaxed.

For example, "Down By The Salley Gardens", "the rose", "reflection", "timeless", "Aesthetic"...

When dining in this relatively soothing atmosphere, your mood will also change. Better
