Visit Landry’s Aquarium Downtown Houston restaurant and you can take a train ride under scenic I-45 and through the parking lots below the freeway. There is actually one part of this train ride that is pretty neat, the shark tunnel.
The train makes a short stop in the 200,000 gallon shark tank tunnel before returning back to the front of the Aquarium amusement park.
is this houston? 
I haven’t done this yet. Were you there all by yourself? It sure looks like it.
Ya my wife, cousins and I were the only people on the last train, in the last car, at 11pm on Friday. The light rays shining thru the water was very cool. Who needs to learn how to SCUBA when you got Landry’s bringing it to you.
