CAF: VENUS AND THE MARS BAR609 Eastlake E, 624-4516This little cafe and bar definitely has a split personality. If you want a laid-back lunch, check out CAF: VENUS' eclectic and delicious menu. If you want to throw back a few after work, check out the adjacent MARS BAR. A galactic theme and a crowd of regulars greet visitors to the Mars Bar, where the bartenders are friendly and pour excellent drinks. The Cascade neighborhood joint also has a full week of entertainment: karaoke on Tuesdays, "Bike Messenger Nights" (that has to be good!) on Thursdays, live music (usually acoustic) all weekend--and they round out the week with free pool on Sundays. Become a regular now, before everyone discovers the place. AMY JENNIGES
