I will never eat ANY type of food with MSG (mono sodium glutamate) as it is classified an an excito-toxin and is NOT good for people....I know many folks (including my dad and brother) who will become extremely ill if they eat food with MSG (Chinese places are usually the biggest offenders though to the credit of many Chinese restaurants will leave it out if requested).....sadly,many available BBQ rubs are loaded with MSG
I have never encountered MSG in any of my regular BBQ haunts in town, but I will always ask if I try a new place....
Cheers,
