I don't know sushi, but i know what i enjoy and i enjoyed this.

I have had take away sushi a couple of timesfrom different places, and the quality is the same. I am sure great sushi places would show me a new world, but i haven't been there so this was fine for me.

Service wasn't bad at all. Efficient and all smiles, they deserved their tip.

Food was abundant, and i liked it, though it was very salmon based.

For £15 i would challenge any of these bad reviewers to find a more filling, better quality and nicer experience in the centre of Soho.

Went for the buffet and found the quality to be awful. The fried food was all tasteless and designed solely to fill you up so that you can't eat as much sushi. The sushi was the worst I have ever had, almost completely salmon based and with all the rolls containing more rice then any others I have had. Even the seaweed wrapping was chewy.

The atmosphere downstairs is poor, nothing like it looks in the photos. You are sandwiched between the kitchen and what appears to be the bin area.

The only plus side of this place is the huge amount of food you are given. Nearly all of it went to waste however.

The worst sushi restaurant I have even been to. Avoid!

I guess this place is most famed for its buffets so that was the option we went for. How it works is that they give you two pieces of paper: one for hot foods which you’re allowed to order 8 items once, and another for sushi which you’re allowed to order as many times as you want.
The hot foods were decent, the typical chicken teriyaki/yakitori/katsu, prawn tempura, fried pork/squid, miso soup, and various vegetables which I’d imagine have never been ticked. Most of these were deep fried and the quality was average, nothing to write home about. The sushi selection was very limited and salmon-based: salmon nigiri/sashimi/iso, California/avocado/cucumber rolls, etc. “Crab” simply meant processed crabsticks and there was no prawn/tuna/eel/octopus/hamachi in sight. The quality of the sushi was not bad, again nothing special but the fish was fresh and the portions were generous. When they say all you can eat they really mean it. You have an hour and a half (plenty, trust me on that one) and you can repeat orders as much as you want. You will leave feeling stuffed. Towards the end of the evening we were simply sending off order after order of salmon nigiri and sashimi with complimentary gari and wasabi.
The décor was certainly very drab and plain – white walls and basic furniture in an underground basement, really not recommended for impressing a date. But then again, why would you bring a date to a buffet? For £14.80 (plus mandatory 12.5% service charge), it’s not too bad, warrants a visit but I wouldn’t really go again.

I went to Hi Sushi last year with friends and received very bad treatment. The food isn't really that good, so if you want nice sushi, head elsewhere. The space is cramped and the minute you walk in, you are rushed in and rushed back out.


They even charge you service charge when you get more service in a fast food place. We argued about the optional service charge and they were very rude, asking us Who brought you the food then? Save your cash for a proper Japanese place, not Hi Sushi.

Hi Sushi isn't the greatest Japanese restaurant but if you're on a budget they do an all-you-can-eat buffet.
I think they actually have branches in Japan, but the food at Hi Sushi wasn't anything spectacular.
