There is an ice house at the front of Qiaogang Style Street. The location is not good, but it is quite famous. I searched online and found many netizens recommend it. I went in to have a look. The decoration is not good and it is very simple, but there are indeed many customers. I ordered two cups of smoothies, which didn't feel sweet. It may be a feature of Beihai. All the stores here are like this. You need to ask for it to be sweeter.
