If you're THAT sensitive, I recommend emailing the Fish House via the link given in the LC Dinner conversation in this very Forum. There's a link to the Fish House page in that very thread (here it is, just clik) and I'm positive there's an email address in there somewhere.

They'll be very interested to know of your Very Low Carb requirement and will discuss it with the cook staff on shift for your mealtime, I'm positive of that. Karen herself, the Executive Chef, will probably contact you, maybe even by Private Message, right here
