The service at Namaste is exponential, the waiters are very kind and courteous. They also speak great English for any visitors who don't speak the best German.
The food is excellent. I have visited this restaurant a few times now, and I usually get the chicken vindaloo and keema nan which are both spectacular! The waiter always warns me that the vindaloo is very spicy, which is just the way I like it. My wife usually gets one of the vegetarian dishes which are also very tasty dishes, and are also much less spicy than the dishes I order.
Definitely stop here for a meal if you are passing through Murnau! You won't regret it!
