Against the warning of a close friend, we decided to try Mary Coyle's tonight. The place was busy & the staff (3 young people and an older man) seemed very disorganized. We weren't offered samples & weren't acknowledged by the person running the register until we asked if we could order. Ice cream was only "o.k" - I doubt they make it in house. My boyfriend ordered a chocolate malt & received a vanilla one.
If you decide to try it out (which I would advise against with so many better ice cream or gelato shops in the valley) ask for it "to go" as seating is limited.
