Obviously this topic has been polarizing to stay the least. Not just with restaurants, but discussions about adult only flights or seats on airlines and adult only movie theater showtimes for instance are also bringing up this topic of discussion.
Should there be more adult only dining options? Well, they always say variety adds spice to life and for restaurants in Disney World, it's no different. I mean, if they had really good food and offered different cuisines, I have no problems with it. But do they need it? Well, that is a question where there is no right or wrong answer for that. But I mean, aside from CRT, there has to be a good reason why Disney provides signature dining options to begin with. I would think most of the signature dining is geared towards adults anyway. Think about it. The entrees at the signature dining are not fine dining prices in the hundreds but they are considerably more expensive than those at a typical TS restaurant. I mean, 40-60 bucks per entree? That is a lot of money no matter how people in your party are dining! Plus for the most part, they are taking basic dinners and making them extraordinary and they only serve one meal of the day, usually dinner and nothing more. Do they have kids menus? Yes, but spending triple digits for food? Most families would never considering doing it usually because of prices or the concern that the food maybe too exquisite for their children or for their own being.
I am not going to engage in a useless debate about "What Would Walt Think?" and all that. But think of it like looking at selections on a regular restaurant menu. People are not going to dine out if a restaurant serves only one food and nothing else. Restaurants never survive that way. Certain dishes people will order more often than others and not everyone is going to order the signature dish or award winning ones. But they need options and to enjoy the experience, they need them! A food item from a restaurant will never please every patron or every food critic but if you're able to strike a balance between appealing to new customers as well as keeping your loyal customers happy and satisfied, then it works better. (That is something I feel a lot of people wish Disney management would start doing more.)
Nevertheless, let me say this: Every action you take is supposed to have a purpose. For a restaurant, you choose to eat at one over other choices for several reasons. Price, menu, good reviews, wanting to spend quality time with family, friends or loved ones and every once in a while, a craving that trumps everything. So you are spending a lot of money to eat out at a place where the restaurant is supposed to be the main focus and that includes the hopefully great tasting food, great drinks, great service, good decor, etc. You're not forking over money to see anything unwanted and that includes rude patrons (Whether they are children or adults), being mistreated unfairly by the restaurant service or anything that causes a scene in a negative way. Or worse, you're the one causing a scene that makes you or your party the subject of unwanted attention! Point is, the main show is what matters, not the unwanted sideshows. Restaurants are no different than seeing a live show or a movie honestly. Do you pay 300 dollars for the theater to see a great play or to see someone talking loudly on a cell phone in the middle of it? I would think all of you would say the first option. Why? Because seeing a show has a purpose of entertainment and enlightening and someone disregarding the civility and manners as well as being unaware of everyone else and the surroundings, whether it's intentional or not, ruins not just your purpose of being entertained but everyone else's. (Maybe even that particular person's experience is also ruined, too.)
Bottom line is, for everyone, be mature and conscientious, be aware of your surroundings and above all, treat all people with respect and civility.
