Had lunch this week at Alsina the latest incarnation of hte restaurant at the garden center at Cornerstone on Arnold Dr on way to Sonoma. It's a south american grilled meat focused menu
Prices for salads with option of adding grilled meat or chicken were around $10 with add $3-4 for meat or chicken. There was also a portobello sandwich, grass fed beef burger and some empanadas and south american cold meats plate in same price range
Main course meat dishes ranged around 18-22$ - grilled pork, steak, kebab
Salad was good and meat nicely done portobello burger was good
They had south american wine by glass and coffee - advertised as cafe con leche - but tasted like latte but decent coffee.
It's an order at hte counter and your food will be brought to you. Tables inside and outside - outside very nicely shaded by olive trees. Service was very slow - large group arrived just in front of us - but I think lot of staff are new to job also.
Overall nice stopping off place between Marin and Sonoma proper. Didnt have time to explore wine tasting and shopping options but looked fun.
