Me and my boyfriend will never be visiting this chain again. The 'eat as much as you want' offer is the most limited menu I have ever seen for a buffet. I had read reviews about how terrible this place was but I wanted to try for myself and the reviews and my predictions were correct.First we were seated upstairs on two tall chairs that had no back to them and were so uncomfortable that I believe they were probably trying to make us leave as soon as possible. Then we were given the sheet of paper that you can order the buffet from with huge circles around all of the rules they have. You can only order 3 'special' types of sashimi and 'fancy' sushi once (tuna and clam is one of them I recall because when it arrived it was literally one piece each. Apparantly that equals a portion for each person) and the rest of the sushi menu is about 8 other items (mostly salmon based...or cucumber roll lol) that you can order 6 different times. My American sushi-loving boyfriend and I didn't get past the 2nd order because the sushi and sashimi is TERRIBLE. The sashimi was still frozen pretty much and if you can't get raw fish right then there's no hope for the rest of the food!! The other hot food menu included about 10 products (mostly chicken based) but they didn't even have dumplings which in my opinion was a shame. You can only order 7 items off this menu ONCE, as was circled with a black pen by our waitress. The portions were apparantly 'for two people' but one chicken stick each is not really a 'portion'.Other customers were complaining about the portions and the response was pretty useless. Also, at the beginning my boyfriend asked for a hot water which was met with the response that they only have green tea, ha!Finally, at the end when me and my boyfriend just wanted to leave as soon as possible because the food was terrible and we felt like we were in a cafe rather than a restaurant, we left the money and mandatory tip on the table and when we said thank you a

This restaurant provided possibly the worst customer service I have ever experienced. Ok, stay with me cause it is actually quite funny: I went there for lunch with a colleague. We had one hour and we thought it would be plenty of time to have some ramen soup. Wrong! We were still waiting 25 minutes later. My friend got up and asked the waitress if we could get take away, as she had to be in the office soon. Waitress said OK. However, five minutes later she brought the food in regular bowls. My friend asked again about the take away and the waitress replied: "YOU WANT TAKE AWAYT NOW????!!" She then proceeded to obviously b*tch in Chinese about is (we could clearly hear the words "take away"). She took the food and brought it back in take away containers. My friend is vegetarian so we asked which food was which. "I DONT KNOW!2, replied the angry waitress. "YOU HAVE TO LOOK INSIDE." Then she pushed me aside and opened one of the containers. It looks like she didn't close it properly cause it started leaking on our way to the office. The story is quite funny, but as you can imagine, I will never ever go to this hole again.

Just visited the Hi Sushi for the first time.
The food was okay, the waiters were very rude and the service was not that good. The seating area was not comfortable at all and once we sat down they told us that we need to leave by 9pm!

Will never come back to eat in, but there is a small chance that I take away sushi from this place.

p.s they add %10 service charge which is not complimentary as they know no one will leave tips because of their ruse behaviour.

Just came back from my "dinner" at Hi Sushi. Me and my boyfriend opted for the Eat as you can buffet but I am not sure if the owners know what eat as you can mean! : We could only choose among 9 cold dishes and among 7 hot dishes. The hod dishes can only be ordered once and the cold one ( sushi, salmon sashimi, salmon nigiri for example.) for three times not more! Moreover, you have a limited time to "enjoy" your meal! Most important according to me the quality is not very good, just ok. 16 £ per head + service , we have been disappointed! We won't come back for sure and I personally don't recommend Hi Sushi for the eat as you can buffet. No proportion quality/price.

I went to this place last week after seeing that they have a sushi buffet.
As a sushi fan, I was pleased with the quantity of the sushi they actually give you but I was disheartened by the variety of choices on offer.
The buffet consisted mostly of salmon, with absolutely no tuna in sight.
The same goes for eel, bass, white fish, squid, octopus. It was none-existent in the buffet.
Instead, we welcome a limited choice of fried foods, deep fried tofu, prawn tempura, chicken teriyaki, deep fried squid roll and we were only allowed to opt for this just the one time.
See it works like this (after being poorly explained by the waitress), you were given two "scrap-like" pieces of paper where you had to tick your choices. One had the selection salmon-this, salmon-that with a california (crap stick meat), roll. The other paper had the fried stuff.
To top the night off, our first and second choices of beer was not available. In the end I ordered purely salmon sashimi.

Stay away from the salmon skin roll.

If you know your sushi, I would prefer it if you stayed away or try the ever superior Korean restaurants that stir in the area.

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.
