As one reviewer has said, it isn't Powell's, but that's not necessarily a disadvantage. For one thing, you won't have to pay for parking. For another, you're generally paying a lower price for the same titles.
I love a good used bookstore, and I can't think of a better place from Portland north to the Canadian order for spending a long time just looking. In some rooms, the shelves stretch to the ceilings, and they're jammed with books. I have every faith that you'll find something you like, often a book you had no idea you'd find.
The only reason I don't give the Tacoma Book Center a five-star rating is that you don't get a lot when you trade your own books in (although it's better than what you'll get at Half Price Books).
All in all, well worth the drive...just make sure you make plenty of time for browsing.
