Four stars is my rating for this authentic, traditional Japanese eaterie, sandwiched near the cosmopolitan, vibrant Clapham High Street, and the more tranquil village setting one can expect from a visit to nearby Clapham Old Town or Northcote Road, Clapham Junction.

I didnt book like one of the other reviewers here, and decided to go on a recommendation from a close family friend.

Polite and attentive as the service was, the most commendable part of the afternoon was the assorted dumpling dishes that accompanied the set menu, ( which definately comes wholly recommended).

The only downside is it is only available Sat & Sun mornings at lunchtimes.The Beef Teriaki juxtaposed with broccoli and bacchoi was quite exquisite.

My fellow guest had it with salmon, and both the portion size and taste left my palate, awaiting more culinary delights from the kitchen.

The prawn tempura (which i ordered twice) and the accompanying sweet and sour sauce was not too overpowering, and the balance of taste and texture was better than expected.

The only poor part about the meal was the rice was not cooked properly for my taste, and a little dry and tasteless, but the teriaki sauce more than made up for this.

Also, the desserts we had of green tea and vanilla ice cream were'nt exhilarating, but didnt take away from quite a pleasurable and well priced afternoon spent in an old local haunt of mine in SW4!!

Unfortunately I have to say Tsunami is the worst restaurant I have been to date. The reason being is the appalling services myself and my group of friends experienced. I had booked a table at the restaurant several days in advance and as we were a large group I also pre-ordered the appetisers to make it easy on the night.

Our table was booked for 7.30pm to be back by 10pm. I ordered in total around 10 dishes for nine people to share. It was a different story when we arrived at the restaurant. We waited for nearly an hour for our appetisers. I had to ask several times, when we were going to be brought out some food as most of the group was extremely hungry by now.

I also had to repeatedly ask for water and drinks to be brought to the table, as after asking for bottles of red and white wine for the table, only one bottle for white arrived, with nine people in the group it did not go around the table. Finally appetisers arrived – ONE plate. I asked are we going to see any more but I was told it was made for sharing!!

That’s all well and good but one plate between nine again does not go very far, never mind that it was chicken which completely excluded the vegetarians in the group. Finally another plate of food arrived “made for sharing”, and then maybe 20 minutes later the third. I again had to again where are the rest of the appetisers that I ordered, and why cant they all come together but I was ignored by the waiter.

To make matters worse, one member of the group received his main straight after this; it came with out any sides and about a half an hour before the rest of the group received their main. Finally mains started to arrive, but still no sides. I waited again for about 30minutes for rice to accompany my fish and in the end sent back the fish because it was cold.

By then we asked to the bill as we had enough of the appalling service. Again this process took about an hour.

Wonderful restaurant. The food is spot on, and complimented by everything else - lovely setting, friendly staff. The perfect place for a romantic meal.

A terrific night, brilliant service awsome food and brilliantly presented.

With many Japanise outlets it can be a bit stuffy but here it's easy going.

Wonderful food, and great service for a very reasonable price, we would thoroughly recomend this place to anyone.

In fact we are going back for a birthday soon, absolutely brilliant!!!

Tsunami in cosmopolitan Clapham does Japanese food in a distinctly different way. Loud pop music of dubious taste rather taints the atmosphere and tends to distract you from the finely cooked and beautifully presented food. Good wine should complement the food and a good ambience too has to enhance the experience. Waiting staff who speak little English or are too busy with their coiffure are a small let down for Tsunami. You'll love the food but, wait for it, the best bit is the washrooms. Drenched in the heady scent of incense with shining Buddhas laughing silently against a soundscape of gentle music, there's something more interesting to take away from Tsunami than the memory of a delightful meal. With a table full of loud chums you'll be fine but don't expect to savour the delicacies in utter refinement - there's a Clapham meets Japan oddity here.

Since it opened the tide has turned at Tsunami and the once friendly, knowledgeable Japanese staff that created a great buzz talking to the many regular Japanese dining there have moved to other shores. Refined chatter has been replaced by loud throbbing music not too conducive to a meal appreciating the delicate flavours of what remains consistently good Japanese food, beautifully presented.

It's not quite Clapham's answer to Buddha Bar and isn't comfortable enough to justify the prices but the unisex washrooms, clouded with incense, oriental music and gleaming Buddha will make one part of your evening memorable. Go once if you are local and go with plenty of friends, but don't make a special journey.
