I am new to the area and I would like to know where you meet singles over the age of 50 in the Baltimore area?

I have been told that Cancun Cantina's and Bamboo Bernie's are places to go on the weekend that are pretty safe and there are single people of all ages. What other places in the Baltimore area have more of an upscale bar/restaurant where there might be jazz music or piano bar with an older crowd?I am new to the area and I would like to know where you meet singles over the age of 50 in the Baltimore area?
