>No, I don't want to get daily emails about this restaurant I'm eating at once while on vacation

I'm a spam nazi...if anyone spams me, I'll remember. I see I still have the [e-mail] active, which means they haven't spammed me yet.

I just had another look at their site, and I don't see any UI issues myself. You find the restaurant, choose date, and it shows you the times available. You then just confirm the details and click COMPLETE RESERVATION. Nothing too skanky about that. There are boxes you can tick in the confirmation page to subscribe to updates, but they are unticked by default (at least in Canada, where it is now illegal to sign people up automatically).
