Quality of both food and service has been steadily going down for last two years. Still in my top 5 places to eat in Tallinn. Not sure how long it will stay there though. Cheap prices for European level. During weekends might be noisy because of Nordic tourist groups.
My favorite place to eat in Tallinn. One of the rare restaurants which have been alive for ages. Excellent Italian food and nice atmosphere. Excellent service. Has never failed me. Reasonable price level for European standards.
Chedi is in my top 5 places to eat in Tallinn. Even Chinese business guest say that it has excellent and authentic asian food. Prices are reasonable for European level. If you cannot get table here try Bocca which is next door.
