I recently went to Red Robin in West Covina after receving a "promotional" email about the Mt. Vesuvius Burger. For every Mt. Vesuvius Burger sold at participating Red Robin, 50 cents would be donated to the National Center For Missing & Exploited Children Foundation between July 26 to September 11, 2011.
This burger consisted of beef, bacon, bleu cheese, Provalone chese, and tangy lava sauce. It was created by a kid who was the grand prize winner in the 2010 Kids Cook Off! Kids are so smart these days and this burger was good!
