Vegan friendly hotels in New York city

Hi all,

My wife and I have been vegan for 7 years now, and I want to surprise her with a trip to New York City for her 30th birthday. I'm planning on doing 5 days in December, ideally in Manhattan. We'll be eating out a lot anyway, but I'd like the option to dine in at the hotel sometimes. Does anyone know hotel options with a good vegan menu? I've got a budget of max around £250/$336 per night for the trip.

Thanks for your help!
