A restaurant with 6 veggie entrees is in Windsor is an amazing find. An African restaurant in Windsor Vermont is an amazing find. Not only is this both of those, but it's fantastic food, that I would be excited to find in any city. I've only been there once and only tasted two of the curries, but the two were both vividly, but very differently, flavored, and both featured perfectly cooked fresh vegetables.
With one train a day in each direction, the proximity to Amtrak isn't all that useful, but the southbound train arrives at 11:23 AM, and the northbound train leaves at 6:20, so you could have lunch at the restaurant and get dinner to go and eat it on the train, after visiting historic sites--I recommend the American Precision Museum.
