California Grill I think.
We've eaten at Coral Reef twice and neither time felt blown away by the food. There always something about each dish that was too overpowering, like the buttery richness of the Mahi Mahi or the weird salty tartness of the catfish. We also found that iwas very loud and we had to wait over 30mins to be seated each time even though we had early ADRs.
California Grill on the other hand was an absolute pleasure. Even though my fiance didn't enjoy her swordfish too much (not a big fan of balsamic, not sure why she ordered it) we both really enjoyed the entire experience. Not to mention I proposed that night so maybe it has a special little something for us.
