Soho is next to our office and as a sushi addict, anything with decent raw fish within a 5 mile radius will be a regular spot for me.
My usual is the 3 amigos (combo of tuna, yellow fish, and salmon) either in a burrito or a bowl. If you're looking to cut some calories, go with the brown rice. If you love wasabi like me, a little bar on the side exists so you can grab some.
Overall, it's a quick little chain spot where you can grab what you want quickly and head out.
