I have done a meta-study of people's opinion

here is the result:
German School with their score:
Alpha + + + + + (Good quality but expensive)
Bellingua + + + + +
Migros + + + - + + (Good for the price)
EB + + + (Good and cheap)
Sprachwelten + +
oekos + +
Benedict - +
LSI - (Good if you want to kiss the teacher)
SKK +
Allemania +
I did not read the post in detail I just schemed it and got some opinions:
Some extracts I collected:
Benedicte is supposed to be the worst of the bunch in Zurich
Migro and in addition to it being the cheapest (and includes books), I have found it very good
EB and it was very good, though I got a bad teacher in one of the classes
Alpha is also supposed to be good, but expensive.
Alpha and they have told me it's very good
I really like the people at Sprachwelten (
www.sprachwelten.ch)
What about inlingua? I went there at the recommendation from a colleague and they seemed very professional
Bellingua is definitive the best after my opinion
I treid LSI, didnt learn any German, kissed the teacher though
I have now been at SKK on Löwenstr, Zürich (
www.skkonline.ch) since April. I would highly reccommend this place.
I recommend Bellingua (on Löwenplatz) very highly and anytime.
I think my teacher at Bellingua was also called Alex, and I can highly recommend him.
Now Im in Migro and in addition to it being the cheapest (and includes books), I have found it very good. A few years ago I was at
Alpha is also supposed to be good, but expensive.
I've been doing Migros for 1 night a week since the beginning of march, beginner level. I'm finding it pretty helpful.
The most frustrating thing about the "Migros Klubschule" German course is that it's slow.
I then went to Sprachwelten which I wholly recommend.
I went to Alpha at stadelhofen for 4 months and found it really good as the classes are quite small,
I went to the Benedict intensiv german course for 6 months in Zurich and have found it great
Well i was in the Migros, is really good and the price good!
i liked oekos the most cause it just teaches german and i found the teachers very good.
Well I went to Oekos.Benedikt and Volkshochschule. Oekos was the best. Benedikt is too big and too bureaurocratic. Volkshochschule is not so good. Oekos is friendly and good relaxed teachers.

I go to EB Zürich, its by far the best school and cheapest and it actually depends on the teachers too
www.eb-zuerich.ch
personally think Alpha is the best !!!
I am currently learning German at Bellingua.
I did a 4 week intensive plus course at Migros. I found it good, but feel i didnt learn as much as i liked.
I've been learning German in Bellingua (Löwenstrasse Zürich) for several months now (intensive class, mornings). I am very happy with the school and plan
i m going to Allemania and we have the same book
EB and it was very good, though I got a bad teacher in one of the classes.
