Treebeards has been serving some of Houston's greatest Cajun food since 1978, and whether you eat at the original Market Square location, grab a seat under the rafters at the "Cloisters" location inside the Christ Church Cathedral, or pick up food from one of two tunnel locations, you're in for a treat. Things gets wild and wooly around noon during the week, when downtown office workers flock to the restaurant's locations for its red beans and rice, seafood gumbo and jambalaya. Smart diners go early or late.
