Do i have to bring a gift?

In my opinion, asking guests to bring the refreshments is boorish and rude. If I were you, I would bring ONE can of soda (for myself), one SMALL bag of snacks (again, for myself), and a gift for the birthday honoree.

Bring a small, inexpensive but useful gift, such as a nice deck of cards, as well as your snack or food contribution. In addition, a "Happy Birthday" card would be nice. Dollar stores usually have decent cards and gift wrap stuff.

Your little present really should be gift wrapped. If others are producing gifts in addition to their foods and snacks, you can too. Otherwise you can keep it in your pocket.

you could make the wine be the birthday gift

I think the gift is the drink/food. Have fun.

A homemade cake will be more than fine. It will serve both as a sweet food she asked

for and a nice gift as well.

Wine and a snack. That's it... If you want to make it interesting bring a board game or some cards.

Just bring the drink or snack. That is good enough.

I'd say your gift is paying for the party, since the guests are providing all the food and drink.

IMO, it's kind of weird, but whatever.

However, if you worry that you'll seem weird if you don't have a gift, too, buy something small--literally small as well as inexpensive--and give it if you see others bearing gifts. Or consider hitting a thrift shop for a pretty glass or ceramic plate or serving dish (they often have lots of those, including silverplate items) and taking your food item on it, leaving it behind as a gift.

it is important to bring snack or food to a friends bday party as for gift thats up to you however dont be surprise if you are the only one who dont bring one...
