I'd go for a multi group classic lever with a backside as beautiful as the front.
Faema Urania for instance.Or President
The Island of course would be the perfect spot for it.

For the past 6 years the espresso machine is in our living room.
My wife loves it and makes entertaining friends and family extremely easy.
I remember in the past spending so much time in the kitchen preparing coffee and missing
the company of friends.It changed the whole thing for me.I now enjoy every moment behind the bar.
I could be preparing coffee drinks all day when surrounded by friends.
And besides, its good to have a full 360 view of your machine.
