We stumbled upon this place. It was almost too good to be true when we saw the prices. It was 15 euro for an all you can eat sushi buffet, as many starters as you'd like that were amazing and all you can drink of any drink. I had so much wine! The sushi was delicious as well so I was very happy! We were not the only ones who had discovered this place, it was sooooo popular!! We had to queue for 15-20 min to get in, but we definitely thought it was worth it. It was so full and lots of people had reserved tables so there were constantly an insane amount of people there as well as coming and going.
It's called Budda Sushi and Japanese Food.
