Have seen multiple acts at Strathmore over the years, from Diana Krall to Joan Obsorne, Joan Rivers, and various classical music performances. It's convenient (on the red line, plus parking is available), and gorgeous. The sound is great, and very little obstructions in terms of views. If you happen to wind up at the very top last row, you might have some of the sound equipment in the way, but it's not that bad.
Food is very good. Price-wise, it is probably on par with what you would pay at a nicer restaurant.
