take it from a cpa...worst investment of your time and money on the planet...not to mention the obvious pitfalls (e.g., unlimited access to top shelf liqour).
it's the fucking hours that will kill you...and, it's a cash business...if you're not there all the time, all of your employees will steal your money and give drinks away to their friends for free...plus, if you enjoy drinking, it's damned difficult to not get high on your own supply.
