We had lunch here on a recent day trip to Sonoma. Loved it! The tacos were so good while cheap (I think 2 dollars each) I'm not an expert by any means as to how authentic they were, but they were delicious. We tried steak tacos, chicken and also potato tacos, along with chips and salsa and horchatas. It was busy, with a mixture of locals and tourists. The menu is posted inside both in English and Spanish. It's not a fancy facility by any means, but it was clean. Food arrived quickly and the lady working was so nice and patiently asked my kids if they wanted any ingredients taken out of the tacos (my teenager was thrilled she could hold the onions) Definitely will eat here again.
