Personally, I think the most cost-effective place to drink tea: West Lake in spring, Shenzhen has one on Sungang Road (Baoan Road), and Yitian has one, just two. There are many Jiangnan snacks to choose from, and it is important to make them on the spot. The important thing is that the quantity is not expensive. 111 yuan for four people. Good environment.
secondly, you can go to the harbour restaurant. There are so many branches of Haigang in Shenzhen that we can't fully count more than 11, but the quality of morning tea, including the price, varies greatly, which is unbelievable. There are two most delicious and expensive ones: the one opposite the water park, Anhui Building, and the one on Binhe Road, Union Square. These two snacks are made on the spot, which are very exquisite and have a good environment, but it usually costs 151-211 yuan to check out four people. The worst one is the one opposite the litchi park on Hongling Road. The taste can't be compared with the above two. The dim sum is steamed there, but the price is also lower. You can go if you don't want to run far.
Tiantian Fishing Port Hotel in Zhenzhong Road is not bad.
I'm afraid the most expensive one is the Phoenix Building in Shengtingyuan Hotel on Huaqiang Road. I used to think it was worth the money, but recently the quality has deteriorated seriously, so people still wait in line, which seems to be a habit.
The price of food at Bao 'an intersection of Shennan Road is the same as that of Fenghuang Building, but the environment and products are not as good as it, so it is not recommended.
The cheapest thing I know is Jinhu Hotel on Jinhu Road (near Yinhu), next to Yinhu Bus Station, and the dim sum is not bad.
