Sounds like a good idea to me. (Although I read somewhere that asking this sort of question isn't guaranteed to get a useful answer anyway: at least some places allegedly feel that if saying "we don't use MSG" will make you buy their food then that's a sufficient reason to say it, and if you collapse the next day then hey, they've already got your money. But I suppose one can but try.)

YES. This makes me really annoyed. Fortunately I can spend two hours over a meal, and my MSG reaction takes about an hour and a half to kick in. :D
