No idea about Helms Deep Games... but Phantom of the Attic in Oakland (it's on Craig Street) is, IMO, the best i nthe area. There is also one in Sq. Hill on Murray Ave called Games Unlimited, but they basically suck. Also, on Babcock Blvd. (which is near McKnight Raod)) there is one called, umm, Game Masters? I've only been there 1-2 times, it's not bad....
