Rudi Lechner's in Woodlake Square on Gessner just north of Westheimer.
If you've ever been there for lunch then you know why it came to mind.
Seriously though, they do have a room available and a good old world style menu, very hospitable folks, etc.
If you go there, tell Rudi he owes Doobie a beer. ;-)
What part of town are you interested in? That would help - this is a big city.
