My last visit to Hibiscus was before Nick had departed. I wouldn't assume his departure would amount to any shortcoming of the food at Hibiscus. Here's a super quick rundown of what we had:
Baked Dungeness Crab Dip: Super, super rich. Very good. Would only recommend if there were four or more at the table. Two people b/w the dip would be too rich for anyone to handle.
Sweet & Spicy Jumbo Rock Shrimp: Stellar appetizer dish. Not a huge shrimp fan, but this one had me smiling.
Spicy Crab Crusted Sea Bass: A solid sea bass dish. A little crab overload after the dungeness dip though.
18 oz. Bone-In sirloin: It was prime. It was good. Cooked perfectly.
Our sides were spinach and the mac & cheese. Both of them were good. The mac & cheese actually tasted better the next day.
Chocolate cake: Completely ludicrous. If you like chocolate cake and you want a lot of it then this is your dessert.
Sorry I can't elaborate any more on the dishes. I seem to be drawing a huge blank today.
I remember our server was spot on solid and timed things perfectly for us. I believe his name was Andrew. The guy also knows a thing or two about wine and paired a couple of really good glasses for us.
Nick hadn't been truly behind the stove for quite sometime so I doubt there's any drop off since your last visit. Garreth Dickey has been manning the ship for a while and Nick was Corp Chef. Agreed on both the crab dip and the sea bass (but there's really no such thing as crab overload is there???) :)
