He's cooking me dinner for the third date, should I bring something??

So I've been seeing this really sweet guy for a week or so, but we're already going to be having our third date today. The last two times we went out to dinner and he paid for everything, and then for today he offered to cook me dinner. I asked if he needed me to bring anything and he said no, but I feel really guilty. I was thinking of maybe grabbing a bottle of wine (we're 21 and 23 lol) or baking cookies but my best friend seemed iffy about me doing that. I don't wanna be too excessive but I feel bad that he's paid for everything and I don't wanna seem ungrateful! Should I bring something tonight (if so, any ideas)??
