If you drive west from downtown along Memorial Drive for about 15 or so miles (all city), it's pine forest the entire route and a lot of wealth. When I lived there, I would always take visitors along that route, and they would be wide eyed in disbelief. Memorial Drive west of Loop 610 winds around through the forest and neighborhoods and is quite beautiful.

For oaks, there's nothing like West University and adjacent neighborhoods. Sunset Blvd might be the best drive. Montrose has a lot of nice streets, too. The streets I like the best are the ones where you feel like you're driving through a tunnel.
