OpenTable.com is great for me, as my assistant will make reservations for me and I or my other half is able to log-in to see either that it was done, or what other reservations are lined up for us in the rest of the week. I'm thinking it was intended so that you could do things "on the fly" without speaking with a human, but I'm indifferent on whether that is a benefit or not.

What I do like is that the site is designed to have a profile set-up that can be managed separately by a "Reservation Maker," as well as "Diner," which like I said above assists when you have an assistant and a daily eat-out regimen.

The points mean nothing to me.

The other great thing is if you're anal, lazy, and/or adventurous, OpenTable will give you a snapshot of where you've eaten in the past so that you are not overly favoring one establishment (trust me, eating out every night makes this useful), helps make suggestions on where to eat in your home city or frequented city, and best of all makes suggestions on where to eat in cities where you are not familiar with the fare.

It works for me.
