On the 49th Floor of the Tangla Hotel building, the China Blue Bar claims to be Tianjin's highest bar. On clear nights, you'll get great views of the city, which lights up at night. There is live music after 9:30 every night (usually jazz and blues).
The chill atmosphere makes it a great spot to kick back and relax with your travel companions over cocktails. The bar offers many of its own speciality cocktails, including the popular 'One Night in Tianjin.'
