What's the parking situation?

It depends on the day. Weekdays street parking normally isn't bad. Weekends lots are going to be at capacity. There is one right next door. Get there early and be prepared to pay high prices for lot parking

I just caught an uber.

So for example a Sunday night would still be bad?

There's always parking within a block or 2.

If you can use Uber, Lyft, train, bus etc., parking is not your friend in DT Seattle

Try parking in Belltown and walking a few blocks

Kyle is correct

No dedicated parking for Showbox. Plenty of garages within walking distance.

There is a small parking lot to the left of the venue and there is an even bigger one over by the Showgirls place across the street
