Yo Sushi at the beginning of summer bought out the Yo burger. They ain't cheap at £8 a meal, for your £8 you can choose between a burger of prawn, fish, chicken, tofu or salmon. They come in a bun of toasted rice with sides of, nori crackers, daikon slaw and misochup.
The crackers are similar to prawn crackers and the slaw is a bit vinegary for me. I liked the misochup sauce.
I had the prawn burger that lacked a lot of prawn I thought. The toasted rice is nice and different and I have not seen anything like it because but with a look round online I found it is so common in parts of Asia that even McDonald's do it. It was nice but for £8 I wouldn't get it again purely because Yo Sushi have so many other things I like so much more.
A few things I recommend at Yo Sushi:
Hot- Miso Soup, Duck Gyoza, Prawn Katsu, Prawn Tempura.
Sushi- Assorted Fish Maki, Spicy Chicken ISO, Crunchy Prawn ISO, Salmon & Avocado Hand Roll. Tuna Nigiri.
