I just remember one bit from a story, where Steve is in a fancy restaurant with someone (I think Pepper?) as friends, and they're brought starters which are tiny- he comments on them being so small, and then laughs and says 'I sound like Thor, don't I?' They reassure him that there is more food coming, these are just appetisers/amuse-bouches/starters and they sit and talk for some time.
It was likely either a gen, Tony/Pepper or Steve/Tony fic, and almost certainly on Ao3.
(Side detail I may be getting muddled from elsewhere: they were possibly in a museum/MoMA, and Tony had rented out the restaurant for them.)
