After reading about OM on this board for a while, I finally got around to trying it last night. Thanks to all the Baltimore Hounds who have mentioned it! Definitely worth many return visits. I especially like the variety presented by the menu, and the fact that the more unusual dishes were listed in English on the standard menu - no need to know the secret handshake or read Chinese to get access to the less common dishes.
And of course, one must mention the food. Good quality, ample portions, and reason to believe that further explorations of the menu will be rewarding.
Again - Thanks Hounds!
