The restaurant is really cute and the staff was super-friendly.
They have a great variety of dishes, a lot of which are vegan - ask if unsure, they will help you. We chose two main dishes and a starter and had difficulties finishing everything.
Usually I am more into vietnamese food, so I can't say whether the food was very authentic for chinese cuisine, but everything we had was tasty. For me, it was a very typical European-Chinese restaurant experience, which I hadn't had since becoming a vegan, so another plus.
This is not the place to go to, if you are looking for fresh and healthy with lots of herbs etc, but if you don't mind fried food - go for it!
Location-wise: it is actually not as far as it seems. From the centre of Rotterdam you can also take the tram no. 20 or 25 and 2, which will take around 20 minutes - a nice ride through the different quarters and suburbs.
