Drinks don´t require any 'extra', but they have a value of 1. Salty Foods or Sweet Foods have a value of 2 and can be decreased (by adversaries) or increased (by you) by adding 'extras'.
Knowing that you have to put all of your cards until everyone played every single card in hands.
You must place a restaurant (picked at random) and a food/drink (also picked at random) that will be the food or drink you sell when you start your restaurant.
After that players will decide who start by any way everyone agrees, then everyone picks a food/drink card and 3 extra cards for the firts 3 turns (you must place one card in yout turn in one restaurant).
Players can´t be attacked more than once per turn (to avoid everyone attacking the same player). In the next turn, anyone can be attacked again.
It´s up to the players to choose when to release new food/drinks in its own restaurant, but everyone must use all cards until the game is over.
I didn´t decide yet when a game ties/ends in a draw, but I´ll test with some friends before deciding.
