Depends on the menu, $80 for 2 is relatively inexpensive;
a few years back I attended some wedding banquets at Shiang Garden,
$1800 -$2500 for a table of ten, 15% gratuity, alcohol extra.
The invitation card included the printed menu with price so we had to
send the "Cash Gift" accordingly. It was 2003-2005.
I know some people in Chinese restaurant business, they are reluctant to sell some $1,000
banquets for no profit, if the customers insist to have dried Abalone, Braised Shark's Fin
and Bird's nest for dessert; they would write it off as promotions.
Call me Old Cake, I never learned to appreciate "Fusion Cuisine" especially Chinese food involved.
Personally, I love the authentic Hakka style rustic home cooking,
however, it is not High-Return of Investment so not many restaurateurs interested in doing it,
considering the salary and opex are not any lower.
