I put Taco Bell's wacky menu experiments to the test. Some meals should return to the lab, while crazy-good items like breakfast tater tots should go national.

• Taco Bell has tested more than a dozen items across the US this year. 
• I've tasted a handful, including the new Breakfast Tater Tots that launched November 16 in Chicago.
• Some items should return to the test lab, but others should go national.

Taco Bell is widely known for testing wacky experimental menu items in various cities nationwide to gauge interest in a possible nationwide release.
