I've been to the Blue Olive Bistro in Tacoma once, on a Saturday night. It's down on Dock Street and is one of the nicer martini bar-type places to go in Tacoma. The coconut prawns are excellent and they have a huge selection of martinis to choose from. The night I went it wasn't particularly crowded, which I didn't enjoy. I like there to be a lot of people where I'm going. If you don't, this could be a good place for you.
The food and drinks are pricey, the decor is awesome (they have an ice bar!), the servers are almost exclusively VERY attractive. It's a decent place to go in Tacoma.
