The highlights of Belltown for me are Macrina Bakery (my husband's favorite thing is the Turtle Brownie - amazing, and my favorite is the Monkey Bread or sour cherry lemon pound cake.) Buy the Macrina cookbook and bake up some of the recipes yourself if you are ambitious - they are worth it. Also entertain a friend or client at El Gaucho steak house, or do a small company function (presentation/dinner) in their private dining area where the food and service was outstanding. If you could get valet parking right in front of these two places and not have to walk around the neighborhood that would be ideal. Stay away from the alleys. Years ago the TV show Frazier was filming a mugging scene in a BellTown alley when I walked by and stopped to watch. The crew said they had to clean up the alley to make it presentable enough to film it as a "bad" alley.
