Anyone who buys a Priority Pass membership, rather than using one bundled with a credit card, has access to the restaurant network. It you go to prioritypass.com *without* logging in you can see the participating restaurants. There are three at SFO:

It looks like Prestige level for US$469 gives the road warriors unlimited access to the restaurants. I wonder why they offer that. Seems like some road warriors would use this >100x per year. Maybe there's a trigger where at some number of visits they cancel the account, give a pro rata refund, and tell the person never to apply again.
