We ate here on our first night at Marshfield. It was the first place we came to on our way into Montpelier, it was dark, so we took it as an easy option.
It's quite a large Chinese restaurant that has as its centrepiece an all-you-can-eat buffet for about $9 a head. They also did a proper menu, and also take-out, I think. We were hungry and went for the buffet (like most everyone else, from what we could see). The quality of this was surprisingly high--there was a good selection that was kept fresh by hardworking members of staff.
It's a high-volume, low-price, informal, bustling type of place, so not the spot for an anniversary dinner, but great for tourists on a budget and locals who can't be bothered to cook tonight. I'd eat here again.
