Loud and proud.Doesn’t everyone feel more compassionate after a martini or three? That’s the notion behind SW’s monthly Happy Hour for Hope, gathering benevolent drinkers at the Bad Monkey Bistro tomorrow night. In fast-changing South Lake Union, with new Amazon towers sprouting left and right, the three-month-old Monkey occupies a low1953 office building at the corner of Harrison St., on the slope where the SLUT heads home to the barn each night. It’s easy to miss, but worth visiting for the regular piano bar nights, karaoke, and sports on TV. But Wednesday night’s focus is on nonprofit networking, and proceeds from the $4 drink menu benefit the Lifelong AIDS Alliance, whose annual Seattle AIDS Walk–mark it down on your calendar–is Sat., Sept. 25 in Volunteer Park. So you’ll have two weeks to recover from your hangover. Bad Monkey Bistro, 400 Boren Ave. N., 467-1111. 5-7 p.m.
