Seattle has fallen head-over-heels for this cozy hole-in-the-ground martini bar. Voted best martini bar, best singles scenes, best 30+ scence, best after work happy hour bar, you name it, Marcus' seems to have won it. Purported to serve 75 varieties of martinis, this is the ideal Pioneer Square spot to light up a cigar and go through a number of martinis before looking to score. And with the drinks at bargain prices, you might want to get a cab ride home.
