I'll admit I'm a bit biased since I live right around the corner and am a regular but Seasons does a delightful Thanksgiving dinner in the same manner as their usual amazing fare. The jams they served along with the bread and cranberry sauce were particular high-points. Seasons has the atmosphere of a comfortable local restaurant (not the least pretentious) yet serving out of this world food. Amazing variety, always changing and inventive menu, and lovely staff. Highly recommend Seasons for anyone visiting or living in Amsterdam.
