It's crunch time. What was once a staggering field of 64 has now been narrowed down to just four great restaurants in Patch's first-ever St. Charles County Munch Madness. 

Your vote will determine which restaurant advances to the Munch Madness championship! 

Munch Madness runs along the same lines as the much-hyped college basketball tournament, except it uses St. Charles County restaurants instead of college basketball squads. 

How do they advance, you ask? It all depends on your vote—on the site, our Facebook page and Twitter feed! To learn more about the tournament CLICK HERE.

Here are some basic rules and regulations:

• Restaurants will advance based on the number of votes they get on each Patch's website and their Facebook and Twitter accounts. The restaurant with the most votes at the end of the matchup will advance.
• Readers can vote by leaving a comment on the posted article for a given matchup. Twitter followers can vote by tagging a Patch's Twitter handle and adding their vote. And Facebook fans can vote by leaving a comment on the Facebook status that coordinates with the given matchup. 
• One vote per user, Twitter follower and Facebook fan. If you follow us on all three platforms like you should, that's three votes!
• Voting periods will be as long as the round in which you are voting.

Here are the Final Four matchups:
