I have been to Marigold Maison several times and I always order the vegetable tikka misala prepared vegan. It was one of my favorite dishes in the entire valley.
A group of us went for dinner on 3/4/2017. I placed my order for vegetable tikka masala and asked that it be made vegan. Shortly after the waiter took our order he returned and said that the vegetable tikka masala can't be made vegan. Another person from the restaurant came to our table and said that they no longer make it vegan because they had to purchase coconut milk in a large size and they had too much waste in their restaurant if not enough people requested vegan which would mean substituting coconut milk for cream.
Their menu clearly states that any vegetarian item can be made vegan. It seems logical that they would stand behind their menu and carry the items needed to veganize dishes. Coconut milk comes in lots of sizes including cans which have a long shelf life.
They have lost me as a customer.
