In retrospect, this may not have been the soundest of buisness strategies.I’ve got a soft spot for restaurants of the convenient, tex-mexy variety. So it’s saddening to see a local chain like Taco Del Mar suffering from such dire financial circumstances. The Seattle based company filed for Chapter 11 bankruptcy protection today, citing liabilities of up to $10 million, which includes $86,875 owed to former president David Huether, and the $56,761 it owes to co-founder David Schmidt.It’s too early to tell what TDM’s long-term prospects might be. But the idea of a future in which Taco Bell is the last tex-mex chain standing makes us shudder.
