Part of my problem with dining is I'm spoiled by Las Vegas. Here, a restaurant is either an exclusive hideaway where reservations would have to be made that morning (but same-day reservations are usually STILL available, unlike most restaurants in WDW) or a place with a dining room that seemingly stretches on forever and ever and dog-gone ever.
Here, they basically have more dining space and more tables than they'd need 95% of the year to make sure that nobody has to sit around and wait. Only when something is happening like a hotel is hosting both a major event and a trade convention at the same time does the place begin to sweat it.
WDW, despite also being a full-sized city of tourism with even more consolidated control over the region than any casino operator, seems to basically treat table and waiter dining as a luxury. You either work hard to get that luxury or else you'll be ordering at a counter for breakfast, lunch, AND dinner. Even in the slow periods and especially if it's in a park.
Meanwhile, you walk up to any cafe, any buffet, most any ethnic food or many steakhouses and you'll hear "Party of #? Why, certainly sir!"
