Shiva

Yes, unfortunately the rice contains butter, most of the breads (as normal in an Indian restaurant though), and two of the vegetarian mains have cream or cheese and the other two have to be requested to be made without butter.

Saying that, I had the aloo palak (spinach/potato dish) with a chapati and it was delicious! The other potentially vegan option is dal. I do recommend it, but only if you know you like either of those two dishes honestly.

Le riz, les pains (sauf le chapati) et les plats contiennent du beurre. J'ai pris le aloo palak (d'épinard et patates) avec un chapati et c'était délicieux! L'autre plat sans crème/fromage est un dal. Il faut demander qu'ils cuisinent le plat sans beurre.

The SHIVA restaurant has been opened for nearly 20 years now and is an institution in town! herself.
There are plenty of vegetarian options. If you're vegan you can easily ask to have the vegetarian dishes without dairy or butter.
Every time I go to the Shiva the chef already knows I want my "baighan burtha" without cream and my naan without butter :-)
The owner is always willing to explain you all the details about his wife's cuisine and advise you how you should properly eat Indian food (spices, etc...).
I went to India a few years ago and I can say Shiva is one of the best Indian cuisine i've ever tasted, definitely!
