Or, Celebs Tuesdays.

Always concerts going on all week.

and I used meetup.ca to find people. you make an account and select activities you like, and low and behold there are hundreds of people with similar interests as yours .
This is not an advertisement. This is a person.
I like chess, poker, hiking, tennis among other things and it gave me a chance to join organized groups and meet people.

Most openings are on a Thursday, and usually lots of people, pluse mingling and talking and booze. Super fun.
