This review is an update..
I FINALLY went for dinner and was not impressed.. $38 for a buffet is an OK deal, but there are honestly not a lot of options for this price and a lot of the food wasn't even ready/plated when I walked up to the table. The dessert area didn't have too many options either, and actually have the same stuff they have during brunch.
Different items that were added for dinner include bone marrow and deep fried oysters, but other than that nothing really stood out for me..
We eat with our eyes first, and although Wicked Spoon is a pretty buffet - its very much lacking variety/taste.
