I love this place for oysters and their buttered king crab.
The best thing that you need to know is they have a happy hour M-Sat that includes $2 champagne glasses and $2 oysters-- and they are nice oysters. I can't go to Casey Moore's anymore because of this alone. They are flown in daily and the wait staff can almost always tell you exactly what to expect.
Also tasty things you should try here:
-absinthe cocktails
-anything with octopus
-squid ink pasta (trust me)
-frog legs
They also have these special events-- they'll put on a 5-course meal special, or recently, a traditional crawfish boil, and they do not disappoint. This is my food "treat yo self" place pretty much all the time.
Probably one of the best seafood places you can find in town.
