Joia Suprema is a Chinese restaurant in the Eixample that rolls two plans into one: eat well and sing. The space is lovely, the portions are generous, and there are showstopping classics to share, like steamed sea bass or Peking duck.What sets it apart is the karaoke: perfect for a group, but also for a date that’s up for a laugh. Good dinner first and, once the ice is broken, you belt something out together.
