Most power amps don't need it and many surge suppressors actually limit the peak current drawn by Class AB amps when they're operating at a high output level. Make sure whatever you use is able to handle what is being demanded. If the amps have a DSP, it's a different issue- most other amps aren't so delicate.
I agree.
The amp's power transformer and power supply are an effective suppressor. An amp with a separate, small power line line connected power supply for DSP or similar functions would be more vulnerable to transients when the main supply is turned OFF. A switch mode power supply would be slightly more vulnerable than the typical brute force analog supply.
It's a little over the top, but one approach might be to install a sub panel for the electronics (which might include computers and such) and use surge suppression on that panel as a sort of "first responder".
In this sort of environment, in addition to the risk from power grid transmitted transients, there will be some local transients created by the restaurant equipment power switching -- especially if the restaurant owner is a cheapskate.
