No not really.
I only use the "food" (snacks or drinks) consumables for the occasional Health / Stamina buffs, but that's about it.
To actually 'eat' with a proper animation while sitting on a stool at food kiosk, or actually being able to interact with the City and go to a night club and sit at the bar and order a drink... now THAT I would do, in order to you know... "Role Play" my character a bit. But none of that can be done at will outside of the few instances in quests where it happens (and usually it's the NPCs you speak to or next to you that are doing it anyway).
So yeah, no I don't really "feed" my V.
