Silber Kuegel has been around since the '60s, started by the same guy who started Moevenpick. Incidentally, Cindy's was inspired by his daughter!

Silber Kugel is definately worth one visit at least

Most Silberkugel outlets have been closed, ZüriTipp say there are only two left now, in Enge and Oerlikon.

Yep read that the other week - not open late evening, so cannot compete with other fast food places, but have to pay similar rent.

Saying that, the one at Enge is packed every lunch time. I do enjoy lunch there after now and then.
