There are a lot of options on the lunch buffet, all vegetarian, so that's a definite plus for Moscow. It's definitely not the best Indian food I've ever had, but it was decent.
There are tags indicating vegan items, but how they're arranged is quite confusing, and you can't tell which item it's pointing to you. You wind up asking "veganska??" and pointing a lot, if you don't speak Russian (I don't).
One of the employees didn't know much about the items on the buffet and kept having to ask another employee if something was vegan when I asked. Seems like a vegetarian cafe with 'vegan' tags would tell its employees which items are the vegan ones.
The food was decent, service was decent. It wasn't specacular by any stretch of the imagination, but it was good.
Cons: Staff don't know what's vegan, "Vegan" signs are confusing
