Device that can stream Netflix?

My dad has a Blu-ray player that is Netflix enabled. He can watch it in his home office only, because that is the only location of said Blu-ray player. I want to set it up for him where he can stream Netflix from two different TVs in separate rooms but also have a menu choice similar to that of the PS3 and Nintendo Wii Netflix App. The only way it works now on his tv is by his instant queue menu. I would like to find a device that can run Netflix with an actual menu, i.e.(new releases, action/adventure, horror, etc.) instead of him having to queue movies from the computer to his Netflix account all the time. The main reason for this is convenience, because he is a quadriplegic and it is difficult for him to have to do all of this himself.

I have looked at the Roku but I am not sure if it offers a menu similar to that of the PS3 or Wii, or if it is just a Netflix 'instant queue' display device only. Does anyone have a device they use or know of one that is capable of doing this without him having to buy a PS3 or Wii? Thanks.
