First of all, you made the right choice to go to Tuanjiehu for dinner! Tuanjiehu Middle Street is called Catering Street, and there are many restaurants!
Better yet:
Jindingxuan Tuanjiehu Branch
Taishuxi tuanjiehu branch
Yongya seafood restaurant
Ziguangyuan
Guo Lin home-cooked dish
Dake teppanyaki
Jianguo restaurant
Shancheng lameizi
You'll see it when you get to Tuanjiehu Middle Street. These hotels are all gathered here.
I have eaten all the above restaurants except Yonghe Yaxian, among which Jindingxuan is famous and the environment is good. It's a little high-end Waiting in line every day is too familiar, and home cooking is more affordable. The owner of Ziguang Garden knows the truth very well. Guo Lin's home cooking feels ordinary, but teppanyaki is new. It used to be the imperial garden, but now it is in charge of Japanese food, and the environment is good. Jianguo Hotel is next to Dake. It's a small restaurant. The environment is not good. Shancheng Spice Girl Hot Pot is OK, and there are often queues.
If the environment is good, I recommend Dake Teppanyaki, which is newly opened and very distinctive. To be affordable, my suggestion is too familiar. Smell? Not much difference!
There is also a new shop called Shanhailou, which seems quite upscale. It's just a distance north of Taijiu, like a private club. Every day, the door is very deserted, and I have never been there.
