Officially, Cinco de Mayo marks the date of a victory in the Franco-Mexico War. Unofficially, it's an excuse to drink margaritas.

The date isn't anywhere near the big deal in Mexico it is at various cities across the U.S. But if it sparks some business at Dallas-area bars and restaurants, then that's not such a bad thing.

In 2018, May 5 is not only Cinco de Mayo but also the Kentucky Derby, so this list has hybrid events that morph from brunch to Derby contests on the very same day. Check out the list:
