We come to San Diego a few times a year to visit my parents and have found over the last few years that my poor mom has become increasingly hard of hearing. She wears hearing aids, but still has a hard go of it, particularly in noisy environments. Loud restaurants, or even slightly noisy ones, have become a big challenge for her and her dining companions (i.e. me and our family). So, my Chowhound challenge: What restaurants can you suggest in the San Diego area that are reasonably quiet? They live in La Jolla, but we're open to suggestions anywhere in the San Diego area, and across the price spectrum. Suggestions for newer, interesting, creative places would be particularly appreciated.
