I cannot understand how it could have been said to have had "some very good business" with figures like these. Anybody can run a business if he doesn't pay his bills, for as long as creditors let him get away with it.
Business doesn't just mean getting the work; it means getting the work, making enough money to pay the bills, and having some left over for a roof over the head and three meals a day. In my opinion, El Zorro was a latter day business train wreck.
Others have succeeded, so it shows it can be done. El Zorro failed lamentably, and the creditors, with the exception of employees who had nowhere to turn, got what was coming to them for their appalling lack of financial control.
Good chiefs don;t necessarily make good restaurant managers. I still have a copy of the financials. The business was very viable had a number of key changes have been made.
