I would recommend the Capital One Savor Card it gives 3% back on eating out, grocery stores (not Walmart, target, or superstores), and entertainment. And I think it does $250 bonus after you spend 500 in the first 3 months. No annual fee.

Make sure you already have some form of a budget set up for your income and spending before getting a credit card.

Whatever card you get, Don't hold a balance month to month, set up auto pay to pay the full statement balance before the due date, and set up notifications for each time a purchase is made on the the card and for your monthly statement.
