Yes yes yes!!! Finally a real natural wine store opens in Marin and with an amazing selection to boot. Highly recommend their monthly wine subscription as well which you can sign up on their website. There are different tiers, and the average bottle price at 4 bottles works out to under $30 - but most importantly you get to go to the tasting each month - 4th Friday of the month, meet winemakers and they often include bottles they don't put on the shelves.
The staff is awesome, the space is so beautiful, there's this cool nook where you can listen to music or just hang for moment, the beer selection is also really good, but I LOVE me some wine at Souvenir. It is a must stop, and if you don't know about natural wine, just ask the staff - my wife and I moved over to drinking natty wine a few years back after a friend in SF introduced us and it's pretty incredible the difference you'll notice. Way less sugar, less sulfites, natural yeast vs. synthetic and lower alcohol %, I believe nearly all are under 12% = this equates to less / no hangovers.
I recall one night with some friends we knocked down about 4 bottles between 4 people, and all of us woke up the next day feeling totally fine. I still like some big, bold Sonoma and Napa reds, but there is a clear difference the next day and after you have a nice skin-contact, orange wine or naturally effervescent red natuaral wine and go back to a big Napa Cab and it will be a night and day difference.
Bonus, they also are an amazing record shop, you will find some very good records here, not cheap ones, but some real classics.
