Cafe Moxie is set to open its doors today on the corner of Main and Centre streets in Vineyard Haven. Owner Michael Ryan said the cafe will be open year-round, every day from 7 a.m. to 10 p.m. with chef Willy Wannamaker preparing American bistro dishes. Mr. Ryan said the credit card system will not be installed until next Friday, so the cafe will only be accepting cash and checks for the first week of business.
