Beer bars (sometimes called taverns or pubs) are legally restricted to selling only beer, and possibly wine or cider. Liquor bars, also simply called bars, also sell hard liquor.
Oregon has weird liquor laws. Taprooms that only sell beer and can't serve spirits are actually pretty common, and they'll have fancy beers brewed in a room behind the counter. (Most of them like to highlight the existence of the brewery by making it visible to the rest of the room.) People don't usually call em "beer bars" but that's exactly what they are.
Haven't heard anyone say chelatchie out loud before, but I live in the pnw and I would guess it would be pronounced cheh-latch-ee, which is similar to how "Wenatchee", a pnw city, is pronounced (not helpful but interesting nonetheless).
I've heard people say it as wrong as Spo-Cane before which was pretty rough
The easiest way to spot someone from out of the area is when it rains, ask them about the weather. We've got a lot of words for rain up here in Washington, so what they pick will say a lot.
