umm, pretty sure that there IS a very large market of people who DO want efficiency as one of the attributes of restaurant customer service, even at the absolute high-end.
in fact, some might say high-end restaurants excel at efficiency and customer service, and technology to bring this to the masses (whether at McD's or at French Laundry) would be welcomed by all.
efficiency != low quality experience; in fact quite the contrary.
They use a lot of science/tech, although not all computers. http://www.newyorker.com/reporting/2012/08/13/120813fa_fact_...
would be great if i could have a few highly-recommended favorites (either theirs, my previous, or friends), and then i can always go "off-road" and dive into the long tail of options if none of those are what i want that evening.
but yes, +1 for CheeseCake Factory.
The other thing I like (at some high-end steak or seafood places) is when they roll a cart out with the meats of the day. Or, Chinese Dim Sum carts. If there were a way for tech to replicate that, I'd be quite happy.
Also for delivery or takeout, there's huge potential to show off daily specials and such.
