We visited the Sand Dollar after a daytrip to Muir Woods, Muir Beach and Stinson Beach. We were planning to eat elsewhere in Stinson Beach, but it was full and the Sand Dollar had some seating on their al fresco area.
We were warmly greeted, directed to our table and served promptly and politely. The restaurant has a children's menu which was helpful, our youngest had a burger ($5) and what a burger - it did not hang around too long. Our other three children decided to have meals from the adult menu, as each was splendid and eaten with relish this was more than acceptable to us "real" adults.
In addition to the staff, the other diners were friendly and there was one other family who very kindly provided some great tips on where to eat on our trip the following day to Napa (Many Thanks - they were good).
We had a very enjoyable time at the Sand Dollar and would recommend it to anyone.
