Going Concern Description	Effective October 1, 2011, the Company acquired majority control of the restaurants in South Africa and began consolidating these operations. In August 2012, the Company opened a restaurant in Budapest, Hungary, and shares 80% of the profits. The Company also shares 49% of the profits in its Hooters restaurant which was opened in January 2012 in Campbelltown, Australia, a suburb of Sydney.			In addition, as announced in March 2013, we will be exiting operating our investment management subsidiary which we believe will save us approximately $50,000 per quarter starting with the second quarter of 2013.
