Five Things: Oct. 20, 2011

1. Starting Oct. 31, in Clarendon will undergo a three-week transformation and will emerge as the Market Tavern, Eater DC reports. The remade restaurant is expected to open by Nov. 21.

2. Democratic state Senate candidate Barbara Favola won two endorsements this week. The Washington Post praised Favola, saying she "would be effective in the Senate from Day 1." The Sun Gazette's support was less glowing: "This is not a slam-dunk endorsement; each candidate brings strengths and weaknesses. On balance, however, we opt for Favola in hopes she will grow in stature in the capital as she has, over the years, on the Arlington board." Clarendon Patch and Ballston Patch do not endorse candidates.

3. ARLNow.com spotted a "now hiring" sign at the new Trader Joe's location in Clarendon. Read more here.

4. Artists from Arlington's sister city Aachen, Germany, will visit later this month and work with local creators on a new site-specific installation at . The creation will be on display Nov. 5 to Dec. 11. This is the second part of an artist exchange; earlier this year, Arlington artists spent 10 days in Aachen to collaborate on installations there.
