Coffee Shops have been a large part of modern culture for quite a while now. The U.S. Constitution was conceived in a coffee shop, and the Declaration of Independence was read publicly in a coffee shop!
There are many advantages that coffee shops have to the community. Not only is it a place for artists(musicians, painters, writers) to come together and display their works. Business minded folks can meet potential clients and discuss new business ventures. Students find a place to get a stimulant and work on their studies.
If you really think about it, coffee shops have had a major cultural impact on our communities. Even if you don't drink coffee, or even visit a coffee shop ever, chances are good that the coffee shops around you have impacted your life in some way.
