We should able to set many prices for each menu items.
One menu item can have various prices base on where it gets ordered. If it gets ordered from Chownow, it may have different price than ordering directly to restaurant. Each menu item can have price#1, price#2, price#3, .... price#10. When this item maps to different menu, we can see which price we want to use on that menu. This way, we don't need to duplicate the same menu for each 3rd party vendor and easy to maintain in the future. Just open the menu item and you can see/modify all prices.
We need the option as well, voted for you guys!
