Talk about a proposal....and one enormous bar tab!  At the Algonquin Hotel in Manhattan, their signature drink,  Martini-On-The-Rock , was once prepared for a marriage proposal.  The cost for the Martini - $10,000!  The drink requires ordering 72 hours in advance because you have to first chose the diamond and ring settings you'd like to rest at the bottom of your martini glass. 

Or - perhaps someone will purchase a $25,000 Sundae to propose!  This golden sundae is a blend of 28 cocoas, including 14 of the most expensive in the world. 

But wait – it’s also infused with 5 grams of edible 23-karat gold and served in a glass goblet lined with a layer of edible gold. 

At the base of the goblet is an 18-karat gold bracelet with 1 carat of white diamonds. The sundae is also topped with whipped cream covered with more gold and a side of La Madeline au Truffle from Knipschildt Chocolatier, which sells for $2,600 a pound.

It is eaten with a gold spoon decorated with white and chocolate-colored diamonds, which can also be taken home.
