The Underground is a well-known venue inside the Drake Hotel on Queen West. It's quite quirky inside and I can imagine it would be fun to see a show there.
I couldn't decide if I liked the sign better in color or black and white, so I decided to post both. I'm sorry for my absence of late, but the new job and the long weekend kept me busier than I imagined. Hopefully I'll get back into a rythm with my blogging soon so there won't be any further lapses.
In the meantime, you can see more signs at Signs, Signs.
