What people say
Sushi restaurants are known for their clean and strong flavors, beautiful presentation, and the ability to cross borders and break with convention. Tsunami, located on Voltaire Road in London, is a prime example of a sushi restaurant that embodies these qualities. The restaurant has recently undergone a facelift with new furniture and a sultry mix of grey, black, and gold hues that make it look ready to reassert itself among Clapham's cognoscenti.
Tsunami is not just any ordinary sushi restaurant; it offers a modern Japanese dining experience that emphasizes clean strong flavors and beautiful presentation. The dishes are modishly intended for grazing and sharing, making it perfect for groups or couples who want to try different things. The zingy 'new-style' salmon sashimi is seared in olive oil and drizzled with ponzu sauce, while the lamb is served with oriental mushrooms, creamed leeks, and wasabi pepper sauce. For those who prefer sushi, there's an 'awesome' selection available.
The restaurant also boasts a swish new bar with a 2 am license at weekends where you can enjoy warm & cold sakès or head for the white wines & cocktails. Tables are in high demand at peak dinner times but early diners get a 20% discount on food from 17:30 - 19:00; at lunchtime you can get out for under £15 per person.
Overall, Tsunami is one of South London's finest Japanese restaurants that offers an exceptional dining experience. With its fresh decor, delicious food options, and excellent service, it's no wonder why this restaurant is so popular among locals and visitors alike.
