This Thursday, Hotwire Coffee (4410 California SW) celebrates its 23rd anniversary, and as is often the case with business anniversaries, customers get the gift(s). Hotwire will offer 23 percent off everything on its menu that day, and plans to serve a limited-edition “23 Latte” to celebrate (with touches of brown sugar, Madagascar vanilla, and cinnamon). Proprietor Jeffrey Silva says the shop will be open 6:30 am to 5 pm that day (September 4).
