We didn't know when we booked, but De Eetstee just received a price: best vegetarian restaurant in The Netherlands, Belgium and Luxembourg, awarded by Gault & Millau.
I can understand the judges. The food was perfect. The staff is very friendly. I ordered juice, and they prepare every glass fresh. For example: apple, pear and cinnamon or carrot, orange and ginger. They serve different kinds of special biological beers, and whines off course. Lots of vegan options. There is an English menu on their web site.
The quality of the food is really great. Very subtle tastes. Nice and original combinations. And the price is very good. You also pay 8 to 9 euro for a starter and around 18 euro for a main course in other 'normal' restaurants in The Netherlands. And in these places the food is just average.
The city of Amersfoort is really worth the visit by the way. I'm from Holland myself, and I never visited before. Beautiful old city, nice restaurants en cafes, lots of things to do. If you visit, you can enjoy yourself for three days or even more. And if I were you, I would book this restaurant every evening :-)
