Something doesn't feel quite right, although it may be okay.

In some countries, it is common for restaurants to ask for a guarantee for some reservations, especially for larger tables or specific events.
It is actually very common for New Year's Eve, as on that evening: * they have only one seating instead of 2 or more, * there is usually a fixed menu with more expensive food that usual * they may have to pay staff more than usual (and/or have more staff) * the cost per person is usually much higher * tables are often larger than usual
So the risk for them in case of a no-show is much higher than usual. And as it's a festive evening and everybody has their own idea of what the best place is for that evening, there would also be a higher rate of no-shows than usual without this. They don't do it for fun, there's a reason behind it.
If you have any doubt about the legitimacy of the e-mail, call them to confirm (using the published number, not the one in the e-mail, of course).
The way they do is often a bit low-tech, but it's not unusual. I've had the cases in Sydney (yes, you want to pay to get a table in front of Harbour Bridge on New Year's Eve), Singapore, and probably other places I don't remember. Probably even had something similar in the US as well, IIRC.
