I checked BLU phones on Best Buy. Best I can tell, they all come with Google Android operating system, connect to the internet, and have cameras front and rear facing:
Same here - I watch some of the cooking shows where they have the "new cuisine" with a chem lab for a kitchen. I wouldn't pay $2 for an all you can eat at one of these cooky "restaurants".
Before I retired I did have to travel somewhat often - I have eaten in restaurants in many parts or the USA, Canada and Mexico, often when I had to entertain customers we went to Michelin starred restaurants, the idea you eat with your eyes to me is just Bullsxxx! I never found one as good as the local restaurants with the home cooking style meals.
When I dined alone I usually questioned a local from the area to ask where they ate and went there.
Every once in a while barcodes and QR-codes are making a comeback. There were quite a few frenzies in the past two or three decades.
Someone would get a fairly obvious idea that many real world transactions can benefit from excluding wetware from it. I.e. instead of humans slowly typing things into computer, then printing it just for another human being able to type it back into another computer one could maybe connect two computers together somehow? Many people conclude that QR codes are a great for this and they even proceed with an implementation just to be crushed by something called "mass [un]adoption".
Transferring bytes between CPUs is a trivial problem, but building a ubiquitous infrastructure apparently isn't and this is what is always forgotten by all kinds of tech enthusiasts. They do tons of assumptions and it always gets them.
A restaurant assumed patrons have a capable phone with them, at all the times, they have an app installed, they have a data plan that connects them to Internet, that everyone is capable of figuring this all out themselves and so on. The restaurant will quickly learn that this is rarely the case and when they figure what would it take to build a totally seamless and transparent system that doesn't have the shortcomings - they'll just get back to printed menus.
I find the QR thing kind of irritating. I guess the theory is that in the time of Covid the less things that have to be transferred hand to hand the better. I usually ask for and get a real menu. One solution I have noticed is single use place mat/menus.
