Haven't been in a couple of years but Monument Inn has always been consistently good, not great, but yes good. If you like cajun style seafood, Floyd's (45 South just past Nasa Rd 1) is one of the best in the area... I really like thier seafood jambalaya and crab bisque.
Tommy's Seafood & Steakhouse and Perry's Steakhouse & Grille are both really good, but $$$! Haven't been yet but several friends have recommended Reef up in Houston's Midtown area, it's upscale but not quite as expensive as the two above.
