Events Places Venues

So we have a good start on the discussion for a date for the meetup. Now we need to figure out a place, it will probably effect the date/time.
I am using the Drupal Meetup Organizing Guide as a starting point.

I think some important things to think about are:
Price: It would nice to find a free/cheap venue. I would be nice not to have to tell people they have to donate

Folks -

Wondering if there is/are any modules that integrate events (think classic community-calendar stuff) with places (think of directories of restaurants, nightclubs, parks, other places where those events might take place).

A "big iron" / proprietary CMS example are the sites being launched by my corporate masters and Gannett: Metromix New York Metromix Denver .

What are some examples of similar event/place driven sites that use one or more Drupal modules?

cheers,
