I am planning to have Indian food this weekend with my girlfriend. Can anyone advise me on some good Indian restaurants around the cornavin-lake side.

There are 2 nice ones we tried about a year ago.
One is called little india i belive near the train station on the same side of the street about 100meteres up on the left if you turn left as you come out.
The other is upstairs straight across the road from the train station cant remember the name sorry

indian resto in Geneva are overpriced to start with, and also not-so-good (I found resto in Basel to be of better quality though these are also over priced IMHO)

There is another one near station e.g. Bombay .

I have heard many people saying that little india is good, never tried though.

If you have car, you could cross the border and go to Ferny-voltaire, there are 2-3 places there as well

A personal favourite is Cafe Ghandi. http://www.gandhi.ch/ They deliver which is perhaps a big plus when you are busy or hoping for a night in.
