LATIN, MATRIPEDICABUS, DO YOU SPEAK IT
Calling in and asking for the next available booking in the next month or 2 (can't remember how far in advance you can book) is the easiest thing to do - basically, being prepared to go in on a weekday for lunch since those time slots are the ones most likely cancelled at the last minute.I'm about an hour away. If I recall, calling in is the best method, yes?
You can also go through Opentable via this method if you want to go through day by day.
If you want a specific date, the "easiest" thing to do is book their private room a year in advance. Though you'll need a party of at least 6 for that.
