check for tripped GFIC outlets and if that doesn't yeild anything, try resetting the breaker again. If still no power then remove the panel from the breaker box and check for voltage out of the breaker with a voltmeter. If voltage then start then start removing outlets on that circuit to see if something burned up. If no voltage then replace the breaker with a new one of the same amperage. The light bulb method is another way but, you'd have to rig one up and is subject to a shock. Short of that, your in for a hefty bill from an electrician to hunt down the cause.
