I haven't had lunch at Cafe Soleil yet...but the bakery happy hour is absolutely worth a visit (maybe even an extra 1/2 star for value!). The espresso drinks are well done (on 4 of 5 occasions) and the savory croissants are lovely, as is the blueberry cream cheese croissant. The homemade lemonade is delicious and refreshing, especially with free refills. I've lucked out on days with blueberry and raspberry lemonade...yum! Local cheeses and farmer's market goods as an added bonus.
Spend a lazy afternoon here, reading the paper or working on a paper. Avoid the hectic farmer's market crowd on Saturdays.
