My wife and boys (ages 6 and 4) are staying at the Hotel Derek near the Galleria this weekend. We have two short days -plan to see the Astros Friday night and the Menil Collection Saturday (whether the boys want to or not). I've read some of the previous posts and need a SHORT list of convenient/Tex-Mex/seafood joints near these places. My main concern is great food and casual atmosphere. Thanks.
