I've been eating a new fusion sushi restaurant near my condo lately, it's called Toyuu Sushi, and it's soooooo delicious. The owner woman working there makes these ones (in the pic below) with tuna, salmon, shrimp all inside with some spicy sauce, WOW, so good, and only 250 baht for that roll in pic below Now they have some promotional card thing too, so if you are repeat customer you get stamps and when it's full get something free
Toyuu Sushi
Location: it's Ratchada soi 7 (Soi Nathong) right in front of Fitness 7 gym.
