I absoutely love the food, but since they've expanded, service has been very spotty. Your best bet is to avoid peak weekend dining hours- you'll end up waiting forever to order and to get the check!
As others have said the service leaves a lot to be desired, but even if you tip well, you'll still be asked to leave almost immediately after paying the bill. Great dosas, though.
I have stopped eating Indian food after a couple of bad experiences in both Istanbul and Amsterdam, but this is unlike any Indian food I've ever had. Don't go here for a dim lit dinner though.
This was my second visit and unfortunately, the service and food left me quite disappointed. They were out of a number of items on the menu and the service was slow. I'm not sure I'll go back again.
