Grilled Whole Fish & Best Lobster & SLS Eats?

Heading to Vegas over Labor Day weekend for my fiancée's birthday. Staying at the SLS and fingers crossed their food venues are pretty good. Most are already sold out though but I'll see if I can get in anywhere.

The fiancée is a big fan of steamed lobster. Also loves crab (like Crustacean has). Also a fan of grilled whole fish. Is Crustacean still there? Any other suggestions for lobster, grilled whole fish or crab?

Looking for somewhere fairly nice for the big birthday dinner...up to $200 for two, drinks included. Also looking for a second night dinner suggestion - ideally not as expensive, $100 for two if possible, drinks included. Preferably on the strip but not opposed to going off of it.

Thanks!
