Saison is high on my list to go next time I'm in SF (along with Benu). The new plans may be a little too harsh on my wallet.
$498 total (including wine, tax, and tip) for the chef's counter (4 people max per day) and $198 regular tasting menu for the main dining room. Benu is $180 for the tasting menu. I'm sure the chef's counter is a truly unique experience, but $500 total per person seems a little high for their current reputation. FYI, I spent less on the extended tasting menu at TFL, although we only had a couple of glasses of wine. But that's for impeccable service, 20+ courses, and a little bragging rights of going to TFL (yes, unfortunately that counts). I guess they're going for a 3 Michelin star for next year. Best of luck to chef Joshua Skenes and company.
I'm from NY so for comparison as well (not looking to stir up any NY vs SF trouble here), the 18-person chef's counter at the newly 3-starred Brooklyn Fare is like $185 a person (without wine), Eleven Madison (Manhattan board's favorite restaurant) is $195 for the tasting menu, and a "weird" comp, the tasting menu at Brooklyn pizza joint, Roberta's (4 people max, only on Wed and Thurs) was $160 when I went in the spring.
I feel like $300, $350 max (in total), I'd consider going.
