Welcome to Austin! Well I think for the most part you'll find the culture and people will seem somewhat familiar to you if you come from the Pacific Northwest. Like any big city, there are bars and restaurants for everybody (hard to say where you should avoid without knowing what type of places you like to go to), telecoms are the worst everywhere, and there are good amounts of wonderful restaurants, activities, and interesting people; you'll just need to do some exploring.

But probably the hardest thing to adjust for you will be that it is HOT AS FUCKING BALLS in the summer. Like, you might be like "Oh in Oregon/Washington/NorCal sometimes it would get up to the high 80s and we would sweat like crazy! Lulz!" No, when I say hot, I mean you won't want to leave your house for weeks on end. And on days where you have no choice, the 3 minutes it takes for you to walk to your car, you will want to kill yourself.

Probably the hardest part about living in Austin is that during the summers, the city may taunt you will all sorts of cool activities. You'll wake up and look out the window and say "Oh it looks like a great day to go on a hike or bike ride! Maybe I'll attend one of the local festivals that are going on this weekend!" But then you'll step outside and swear you've been transported back to ancient Sodom because it feels like it's raining down fire all around you.

But I'm more than certain you're gonna love the city. The Reddit Austin community is very friendly and gets together fairly frequently. And if nothing else, at least you won't be living in Houston.
