The West Seattle Blog reports that Prost! on Greenwood Avenue is opening a sister pub, Prost! West Seattle, in the next month or so. The main difference between the two is that Prost! West Seattle will welcome the under-21 crowd as well. There’s quite a thread of comments on the West Seattle Blog debating the merits of allowing children in a bar, but the owner, Chris, says the new pub won’t exactly cater to kids (no booster seats, crayons or kids’ menu), but he wants it to be family-friendly in true European style.
