10h layover in Beijing

I have a 10h 40 minutes long layover in Beijing Capital international airport (terminal 3). I have a Polish passport so I'm visa free up to 15 days (idk if that helps anything more than regular 144h transit visa). Rather than sitting there for that long I thought about getting to the center (or anything like that, I think everything will be closed around 5pm anyway) and maybe grabbing something to eat or just hang around for an hour or two and go back. I arrive at 16:10 and my flight is at 02:50. Anyone had similar experience recently? I saw a 4 months old post with similar situation but everyone were talking about being (possibly) rejected on 144h transit visa and, well, I suppose I don't even need it. Thanks a lot 谢谢
