I consider myself to have graduated with a Phd when it comes to sampling Indian lunchtime buffets in Lausanne.
Would I have rated this place 5 stars back home in the UK? Hell no!
However, for Switzerland and Lausanne this place is quite good and I thought the service, ambience and food quality were reasonable. 20 Chf buys you a drink, coffee and something edible and based upon this I would give 5 stars
