Went there last night with my wife. It was a warm night so all the bars and restaurants on the river were absolutely packed. Tentazioni still had a few tables available, I was amazed (and a bit worried). This was the third time I have been and I was once again very impressed. To me, this is the best Italian restaurant in London. Food is excellent, service is attentive and the restaurant is very intimate. I had the tasting menu for £41 (excl wine) and this is a 2.5 hour Italian culinary experience. If you decide to take this, try to not eat too much bread, because the dishes are not small and you will want to eat everything! Highly recommended.
