Where to buy fresh black truffles in the Bay Area?
If all else fails, check out The King of Mushrooms:
he does wholesale (and some retail) of mushrooms, including truffles. Todd supplies many of the better restaurants in the Bay Area, so whatever that means to you about quality.....
I know him from a completely different part of his life. (FYI)
The Pasta Shop imports truffles once in a while, but before they get a shipment they send out a blast to their truffle email list and people can reserve them. I haven't gotten a blast in a while, so I don't think they have any shipments coming soon.
This is a good way to do it, since you know you're getting as fresh a truffle as possible, but it doesn't work when you want a truffle on a particular day.
