We almost didn't go to Krazy Lobster after I saw this but decided to do so anyway because the port area was so crowded.
The beach area definitely looks like the second picture, but we were seated in an area with both a table/palapa and loungers right in front. I think it was kind of where the boats are above. Drinks were a bit weak (as they usually are at these kinds of places), but we had a blast. Lobster nachos were tasty, and the shade was perfect.
We had only two complaints. First, lobster nachos are actually not on the menu, so we asked how much they'd be. We were told 25, but we were charged 30. The server was apologetic but said his boss wouldn't fix it.
Also, the bathrooms are downright disgusting. As Ace Ventura would say, "Do NOT go in there."
