Hmm, I haven't been to either of those, but it's strange that they would not note it for you. Did you call the restaurants directly (as in not just asking when you made the ADR?). I'm sure you will be just fine asking at the podium, but you may want to try calling again on the phone and see if you get someone more accommodating. I always have them note it any place that I think may have limited options, and sometimes the chef will even come out to discuss what you'd like as an alternative. Again, if they won't do it for you, I really wouldn't worry, as I'm sure both places have many ingredients on hand to make something delicious! Have fun!
