I haven't been myself, but Le Comptoir du Vin in Station North could potentially be a lot of fun! It's a small restaurant with a rotating menu (however, they're kind of inflexible for dietary substitutions). My friends did enjoy the food and experience a lot!

On the other hand, I was treated to a great dinner at Cookhouse earlier this year. We went late in the evening, but the restaurant was comfortably dark and not too noisy. Their current menu seems to have a number of gluten free entrees! Pricy, but a nice flex for an anniversary dinner.
