2) Do some homework before you go.
The menus are online HERE so you can make a list of some dishes that intrigue you. Plus, if you or your friends have any food allergies, likes or dislikes, you can figure that out before you go and you won't be disappointed. Knowing the food offerings and also how much they cost will help you figure out how much money you'll need for this food adventure. Make a list of some things you really want to try. The food locations are divided up into 5 main booths and 1 alcoholic beverage booth. There is usually some sort of protein, appetizer and dessert offering. Suggested wine pairings are available, too.
If you want to see detailed pictures and some reviews, I recommend visiting the Disney Food Blog (not official) and read their post. Bookmark their site if you are a Disney foodie. They cover just about anything Disneyland and Walt Disney World food topics.
3) Create a food & wine budget.
Purchase a wearable event wristband. It will help you stay on a budget and make each food transaction easier. You won't be pulling out your wallet at every location. There are several designated locations to purchase these. You decide how much you put on it (if you did your homework, you'll know how much $$ you need). If you don't use it all up, you can still use it at any food or store location. It works like a gift card.
