This is a compile time error. Make sure you spelt the variable name correctly and that it exists in the class definition for Meal.

Additionally, return m_KitchenNote; will not throw any exceptions, so there is no need for a try/catch here.

Unhandled exception at 0x78212c57 (mfc80d.dll) in ProNtr.exe: 0xC0000005: Access violation reading location 0x00000000. I am getting this exception and the green arrow points to the return m_KitchenNote; statement.

Try putting the try/catch back, but do it as Mehdi suggests.
I suspect, however that it is not really this function causing the issue, but it is how you are calling it.

Could you please update your question to include the few lines of code preceding the function call.

You can browse the call stack by going to Debug>Windows>Call Stack. Double click on a function in the list to go to it.

catch(Exception *e)
{
}
