Why locals love it
Free of any flavor enhancers, gluten or other stuff you normally find in one of Vienna's many Chinese places. It's one of very few Asian places in the vicinity. The owners are very nice and fun, they just love cooking food and taking care of plants (there are a lot).
Why you should visit it
It's a small place but normally not too full to still find a free table. Here you can get authentic and fantastic food, both vegetarian or vegan but they also serve meat. One can really feel how enthusiastic they are about their food and cooking for you. They have a cheaper lunch menu but prices are very reasonable for Vienna anyhow.
Their fish and tofu dishes are remarkable, also the eggplant one. Go there on your birthday and let them surprise you :p
