I would buy the space next to the breakfast/lunch cafe in my neighborhood and make it a supper and drinks place that opened right when they close each day. Bribe whoever it is you have to to get a liquor license, hire a few people, pay really well, have no set menu but a supper service and then a few hours of drinks and small plates, close by midnight. Oh and a big cappuccino machine of course, coffee too.
I know this doesn't sound impossible but it's out of my reach and is what I'd do if we got a big windfall, like more than we need.
