Yes, I've seen one in Oerlikon but I don't know the address. But if you take the train to Oerlikon, get on tram 10 or 14 towards the city and get off at Salersteig (2 stops). You will have passed it on the right-hand-side, before getting to this tram stop. So when you get off, you will have to walk back a bit.

I'm hoping someone would be able to help out here with the address? It's around the corner where laughing lemon give their cooking classes.
