Not sure you have the space for stools

Not sure it would be a comfortable spot for someone to sit given the leg room but you could hunt down a few backless modern black stools and see what you thought - it would be nice if they are shallow so you could tuck them away under the overhang

These are from Allmodern - black but have some warmth with the seat

Is it me? It doesn't look like you have an overhang for barstools.

@kandrewspa agree I didn't think there was an overhang either

I couldn't tell if there was a glass shelf that created a bit of an overhang?
