Let the people of DubSea bikes pimp your ride (and by that we mean make minor repairs) free of charge. As long as you're getting something for free, bring a donation to the White Center Food Bank (if you don't, you're kind of a jerk). Free.
Jesus god, this sounds good: Dinner for two in the form of a whole two-pound Dungeness crab—wok-seared with tamarind sauce, Singaporean yellow curry, scallions and ginger, or Saigon salt-and-pepper style—served with a fresh mango and papaya salad for $30, every Sunday and Monday night at Monsoon. Also: Bottles of wine, 30 percent off. See you there. $30.
Wallingford's Moon Temple is one of the highest-quality dive bars this city is privileged to still contain. Trivia night here is fueled by strong-ass drinks, and probably concomitantly fun. Long live the Moon Temple! $2 (registration fee per player).
