Currently in Tianjin looking to celebrate a friends birthday with Champagne or sparkling wine.

For wine, I recommend Dynasty Wine Company to you. You will have a wide selection there and the quality is good. It is located at no. 29, Jinwei Highway, Beichen District. Their contact is 86-022－26998888 by the way.

In addition, you can go to local large supermarkets to find what you want, like Carrefour (I know the Longcheng branch is at B1, Xin'an Mall, no. 138, Dongmalu, Nankai District) and Walmart (there is a branch at no. 68, Huachang Street, Hedong District). Go for a try!
