  1. You can host a webserver on a Raspberry Pi. I don't know what you're doing with your setup but you absolutely do not need hundreds of watts to serve a few hundred KB worth of static webpage or PDF file. This website is powered by a 30 watt solar panel attached to a car battery on some guy's apartment balcony. As of writing its at 71% charge.

  2. An Ampere Altra Max CPU has 128 ARM cores (the same architecture that a raspberry pi uses), with a 250 watt max TDP. That works out to about 2 watts per core. Each of those cores is more than enough to serve a little static webpage on its own, but in reality since a lot of these sites get less than 200 hits per day the power cost can be amortized over thousands of them, and the individual cores can go to sleep if there's still not enough work to do. Go ahead and multiply that number by 4 for failover if you want, its still not a lot. (Not that the restaurant knows or cares about any of this, all this would be decided by a team of people at a massive IT company that the restaurant bought webpage hosting from).
