Tea Shop in Harvest Moon 3DS: A New Beginning is set up at the same location as Neil's animal booth and Rod's pet shop, in the plaza of the village main area. Olivia will sell drinks and sweet desserts for you to eat. Similar to Clement's restaurant, the items you buy from her shop are eaten at the time of purchase. She doesn't have a to-go menu, but you can order as many items as you'd like each day. Some of her menu items only appear after you've completed Town Restoration Plan #5.
Olivia's Tea Shop is open on Friday, Saturday and Sunday from 10:00 am to 6:00 pm. But her shop will be closed on a rainy day.
