ANYONE HEADING DOWNTOWN on Sunday should stick around until 7 p.m. when well-known contemporary swing band Big Bad Voodoo Daddy is scheduled to play at the foot of City Hall and march with a percussion section in tow all the way to the grand opening of the Watermark restaurant at Chestnut and Main.

Once there, they'll play from the open rooftop bar in a event somewhat reminiscent of when the Beatles played from the rooftop of Apple studios. Music fans take note; the show is free.

I went to the "soft opening" of the Watermark on Monday night. Owners Mark and Kathy Hartley and Jim Rice have a hit on their hands. If you want to go, better make reservations. I predict it will be packed. The food is great and the three dining levels are remarkably comfortable and full of historic ambiance. My favorite spot is the rooftop bar W20 with its retractable roof, comfy banquets, fireplace, aquarium and great views. A private dining room with its own terrace is tucked in the back.

Hartley, a musical agent who represents many top acts, was a major force behind the recent Kevin Costner event Downtown and promises to bring even more great entertainment our way.

The Watermark is a much-anticipated and welcome addition to our bustling Downtown.
