Happy Sushi offers a wide variety of sushi, it is fresh and mostly delicious however there are a few things I don't really like - the sushi with philadelphia cheese is not real sushi but they have lots and lots of it. It is also really ridiculous to offer Bulgarian shopska salad as a sushi roll only to fit it in the concept of the restaurant - should have been left out. Some of the desserts are not particularly fascinating, the chocolate souffle is great though.
All in all great sushi for Bulgaria, good sushi for worldwide standards. Attentive service, clean, sleek design. Affordable for Bulgarians, cheap for foreigners. Will go back.
