Not to be confused with Soyo, the korean restaurant, Soho has excellent sushi and other dishes and, during happy hour (4-6 weekdays+sat), great prices.
Everything is good, but favorites include the firecracker roll (it's fiery!) and the ika geso (it's kind of like calamari, but Asian). The amaebi sushi/sashimi is excellent and comes with the heads.
As a spoiled Californian, I am continually amazed by the high quality and amazing flavors of the sushi here in Vegas, and Soho is no exception.
This is an excellent restaurant both for a classy date night or for a casual group of friends. Best to come with a large group if you can to sample more items!
