    I was really disappointed as didn’t get to have anything bar water. I waited for 20 mins for a cocktail despite the restaurant being empty. I had to get up and ask about 10 mins and the waitress said that they have a new barman, so sorry for the delay and it will be with me shortly. I waited another 10 mins and left, my friend was running late. So I needed a drink to relax and yet waiting that long for a cocktail when there were only 5 people in the restaurant was very disappointing and not sure why they would only have 1 new barman man on a Friday night. Such a shame as me and my friend were really looking forward to the meal! They didn’t even come to apologise, I had to get up and go to them!

    Dear Ethan, We are truly sorry to hear about your experience and sincerely apologise for the disappointment caused. We appreciate that you chose to spend your evening with us and are truly sorry that we did not provide the experience you were hoping for., and we are very sorry that we failed to provide the experience you expected and deserved. Waiting so long for a cocktail is understandably frustrating, and we are equally sorry that you had to approach the team yourself and were not kept informed. This is not the standard of service we strive to provide. We sincerely hope you will give us another opportunity to welcome you back and provide the service and experience you deserve. Kind Regards, Tsunami Clapham Team.

    The tempura was outstanding -all of the different items were cooked perfectly, with a light crispy coating. The white wine was well chosen The dragon roll was merely ok - each bite was bigger than my mouth, and the avocado wasn't quite ripe. the hot sake wasn't hot, and it was very sweet. The service was efficient and friendly. Multiple servers helped at our table, and all were very good.

    Food was good. Service was poor. Things coming at wrong times, order mix up, waitstaff being passive aggressive, slow drink reorders. Bit off putting it’s also a shisha bar.
