> I could see some features becoming quite annoying, especially if you have to click through a bunch of upsells to finally add item to order.
...which is exactly what would happen, because you can measure how many times the upsell works, but you can't easily measure how many people stop going to your restaurant as a result of this crap, and companies will literally kill people if they can find metrics to show it's profitable.
> I think places could get creative though, for example leave comments for the chef about the meal, make specific requests which the prep team can respond to, have the chef speak about the daily specials in video rather than have a wait staff regurgitate them after having never tried them.
Having worked in food service in the past, the last thing chefs want is comments on the meal from customers. The ignorance and rudeness of the general public when it comes to food is astounding.
The chef speaking about the daily specials might be the only reasonable idea here, but my gut feel is that the only people who would use this would be tech folks interested in the feature, not end users. I don't think this is probably enough of a value add to be worth implementing.
