Pleasure Island or Sabine pass are good. Pleasure Island you can fish the revetment walls and the pass at the end of the Island. People say the north revetment wall is better, but I always seem to do better down south. I usually just drive down the island until I see bait fish moving along the rocks.
Sabine pass, you can fish all along the pass down, keith lake, to the jetty. I like taking my boys down by the jetty and fishing the area right before you reach the jetty.
I have heard people are having luck fishing the ship channel on the west side of Pleasure Island.
Hope this helps, I have not been out there since this summer. I have been fishing Trinity Bay. Welcome to South East Texas and I hope you like dirty water.
