Happy Sushi

I recently visited Happy Sushi, expecting a delightful culinary journey but instead embarked on a gastronomic misadventure.

Imagine my dismay when I realized the sushi had about as much flavor as a cardboard diet. The tuna, which I had eagerly anticipated, sported a brown hue that reminded me of a neglected autumn leaf, a sure sign of its extensive vacation in the fridge. To add to the comedy of errors, our food arrived in under two minutes, faster than a rabbit on a caffeine rush, signaling it wasn't freshly made but rather a reheated relic from a bygone era. Their "all-in" formula seemed more like a 'get-out-quick' scheme.

After courageously battling through a single dish, we decided to retreat, sparing our taste buds any further trauma. This place makes a convincing argument for a lifetime of fast food loyalty.

Interesting place which is surprisingly modern on the inside eventhough the outside doesn't look too appealing. The atmosohere is quite nice with the asian music and the really friendly staff. We had some good Asahi beer and two bowls of Ramen. Mine was with fried pork while the other one was with shrimp tempura. With the Ramen came 4 gyoza. The quality of both were pretty good and definitely satisfying for a quick lunch out in the city.

We payed about 17 Euros for one bowl so you can make your own opinion on the price.
I would definitely suggest checking the place out as It's pretty good :)

Happy Sushi offered the best tasting ramen I've had in Luxembourg yet. The service was quick, the servers were understanding, potion size was apt, all and all wonderful experience and would definitely revisit the joint!

The quality is good but the rolls are too big for my taste. Everyone at the restaurant is super friendly and helpfull and the space is quite cozy. All you can eat is 20€ at lunch and 30€ at dinner

I went for lunch to enjoy some sushi. I was completely disappointed with the quality and the limited choice for the all you cam eat formula costing 20 euros. Most ingredients are not fresh but unfrozed.

We were very excited to try their all-you-can-eat formula for 25€ which sounds very attractive given all the options. Most of the dishes we ordered were quite ok but never exceptional. I am glad I could order a smaller ramen but I felt like I had an instant noodle soup instead, compared to a friend who ordered an actual portion. Sushis were also average and a bit too big to my taste. Many things we ordered never came which was quite frustrating. It is still a good place to go if you are very hungry and want to order many different things without being very picky taste wise.

Dining at Happy Sushi unfortunately wasn't too pleasant experience. The staff is incredibly nice and friendly but that's it.
Menu is performed on tablets but it's very chaotic. You can't understand what they mean and in the end you choose just randomly praying for your food to be good. But it isn't. My ramen was faint, tasted like instant miso soup. I also didn't like prawns nor gyoza which I usually love. There's just simply something bad about its taste.
Restaurant is overall quite dirty, dusty and toilets are terribly smelly - you can smell them even in the back seats.
I don't recommend this place.

Located in the city center of Luxembourg, we tried it out randomly. From outside it doesn't look big, but it actually offers quiet some sitting possibilities. Staff was attentive, got us a seat, served quickly and was mostly polite. Really liked the innovative ordering system via a tablet! Good overview and easy to handle. The portions were big, so a fair cost value. Sushi was fresh, tasty and was served with a miso soup beforehand. Tea ordered was prepared with fresh ingredients. Sauses were available and the tables kindly decorated.
The atmosphere was calm and unspectacular.
You saw the staff constantly running back & forth, serving quickly. The toilets are located in the basement and were clean.
Overall, it had something of a hidden pearl. From outside, perhaps bit too much advertising, but definitely an eye-catcher. Liked it in general and will definitely come back, being next time in Luxembourg.
