I really like Samurai Sam's. I wish there were more in the East Valley.
There are two dishes that I like. The Steak Rice Bowl and the Steak Yaki Soba (sp). Both are excellent for lunch. The steak is lean and tasty. Many other places I go to that have similiar dishes always seem to have a cheaper more fatty steak. This has not been my experience at Samurai Sam's. Also, their teriyaki is a little sweet but very good. They are great about giving extra if needed.
Overall, I'm very happy with Samurai Sam's and would recommend it as a good value for lunch.
