My family rarely goes out to restaurants anymore, not because we don't love restaurants, but because it's more fun to cook at home.
Most restaurant food needs to be simple and easy so they can get you in and out quick.
That really depends on your personality. Not only is "people watching" not my thing, but the idea of other people "people watching" me is terrifyingly uncomfortable. Sends shivers down my spine level of discomfort. Please don't watch me while I eat. Some of us find the idea of "making small talk" with anyone, let alone wait staff, to be inherently uncomfortable.
For others, eating is a social activity, or an opportunity to socialize, and they like that. Some people feel "trapped" if they are cooped up inside their homes for too long, and need reasons to "get out of the house." That sounds like you, and that's great. Nothing wrong with it at all and you should enjoy eating out as much as you like. For others such as myself, who are introverted and find great comfort in the solitude of our homes, the reasons that you find eating out to be comfortable are the same reasons we find eating out to be uncomfortable.
If it makes you feel any better, and maybe I'm only speaking for myself, but when I people watch, I'm barely paying attention, and I'm never really watching people actually eating. It's the activities around the eating, mostly just walking and talking (this is why I really like European sidewalk cafes, you get an endless river of people passing by to watch). I'm not taking detailed notes on anything, and definitely not bite sizes, how many times you chew, how messy you are etc. That's all too close for my own comfort. Couldn't care less about that stuff. Probably the most info I retain is new ideas on how to dress myself, outside of exceptional or weird situations that might arise in public. Which, OK, in the context of this thread, I might notice the people carrying two or more heaping mountains of food to their table at a time.
But it's when I'm not seeking those things, when I want to enjoy a meal or a private conversation, then I start to a) feel protective of my privacy (and yes I know, restaurant = public place) and b) I just have no interest in the type of socializing that we're talking about (making small talk with the wait staff etc.).
In other words I just want to be left alone, and I find the concept of people "people watching" me while I eat or go about my daily business to be, well, creepy. If I'm asking for attention it's different. If I'm enjoying a meal with my wife, leave me alone.
I will add, however, that the privacy element is probably a bit more "extreme" for me than others because of having experiences as a child where privacy and boundaries, when there was an expectation of privacy, was violated. And so I am more concerned with privacy than probably even the typical tinfoil hat wearing techie who is paranoid about Internet and device privacy. That's undoubtedly where the thought of people "people watching" me while I eat at a restaurant creeps me the hell out comes from.
I am unduly paranoid about my privacy when working from my home office, and I absolutely hate anyone approaching my screen to look and ask what I’m working on. I always have to catch myself to avoid snapping at my wife when she barges in. In my case its probably that my father used to aggressively check our screens and say like “oh who is that girl you’re talking to on Facebook etc” (not in a fun way, kind of ridiculing or trying to embarass you kind of way).
Its completely irrational but the back of my head is yelling “an authority figure is about to come tease, ridicule, question you etc”. So I definitely see where you’re coming from.
So now I think more people then ever will be having restaurant food at comfort of home and not worrying about traffic, driving, cabs, parking, crowd, one more beer or wine glass etc.
For you. If a person says they don’t like eating out because it’s uncomfortable, you can trust they know whether they are uncomfortable or not.
I don’t like loud, busy places. It’s great when I can have a meal at a restaurant when it’s not packed, but you never know until you get there.
Re: baby: If there's an Ikea near you, you might want to try that. Around here, they typically are very well-prepared for small children (say, 1+). Basically, all of the cutlery and china they sell for kids is available for use in the restaurant. And they have play areas integrated into the dining area - kids play and parents can eat.
With friends, family or coworkers, eating out is fantastic and a fun social activity.
Alone, it's awkward, uncomfortable and unpleasant.
If I'm not with someone, I'd rather it be delivered.
People never ate out because of the food. They ate out because of the dining experience.
You can make better meals, cheaper, at home, in less time than it takes to go out. Yet people still dined out.
And, they pay a premium for it. There is no sense in paying a premium for home delivery, because you are getting substandard meals[1].
[1] Few dishes travel well in a bag, even if it's packaged properly and delivered quickly - steam rising off hot food that is not ventilated causes things to go soggy. If you do ventilate it, then it goes cold in minutes while traveling. Then reheating the food makes it less nice than it was when cooked. Hence, all delivered food tend to be slightly different to eating it off a plate when it is freshly cooked. Even pizzas suffer from being steamed while traveling.
It isn't as good as a home cooked meal but it is a lot better than the awful TV dinners I rarely ate back in the 80s.
This is going to be highly dependent on your local restaurants and what you like to eat. I can't make better bbq or pizza than the restaurants near me. I can make either of those pretty well, but not faster. I can make a pretty good burger, competitive with almost all the restaurants near me, but I can't make French fries as good as a restaurant with a fryer.
Because you can eat it in the comfort of your own home, instead of the discomfort of an unfamiliar place surrounded by strangers.
It may just be me but I really do not like eating in public.
