Bar mini-game
Any time after you acquire Claire in your party, go to the bar where you first met her. Talk to the women in black and red behind the counter. You will then be given the option to have a drinking contest with Claire for $100. If you win, the women will give you a piece of map. She gives you up to six pieces of the map, then she begins to give you Phoenix Potions. The game controls are simple. The objective is to have your drinking bar lower than Claire's.

Extra money
After week 1, when you play the song to the Princess, play Eternal Love instead. Afterwards, quickly run to the public office and talk to the boy at the desk on the right. If you got an A on the song, you will get $15,000 instead of $10,000.
