Clear Lake area?
Can you clarify "near?" There are a few unique and very good places near like T-Bone Tom's in Kemah, Perry & Son's (Meat) Market and Grille on Scarsdale, Gilhooley's for oysters and seafood in San Leon. Tookie's in Seabrook gets widespread love for burgers and the like. That is the only one I haven't been to yet. Hope you find some good eats!
