We ate at Le Cellier as vegetarian, non-mushroom eaters and had no problems. You may want to have it noted on your reservation but definitely inform them when you are seated that you have a dietary restrictions/vegetarian in your party. A chef will come to your table to work with your cousin on what she would like to eat. They are really great about it!
I would think the same would apply to Ohana’s. We have dined at Sci-Fi, Mama Melroses, Liberty Tree, 50’s Prime Time, CRT, Le Cellier, Coral Reef, Hoopr Dee Doo Review, Tusker House, Akershus, Nine Dragons, San Angel Inn, Tonys, Boma, Marrakesh, Rose and Crown and others with no problems.
The only restaurant we encountered a “problem” was at Chefs De France, the chef didn’t seem to know what the ingredients were in some of the dishes :huh:. Maybe a bad night?
