The Atlantic Wear in the lobby of Beach Club resort has groceries, dry goods, snacks and a variety of beverages available from 8:00a.m. to 11:00p.m. daily.
For pastries & coffee I guess...not 100% sure but maybe Beaches & Cream Soda Shop...We always go over to The Boardwalk Bakery 6:00a.m. to 11:00p.m. they have muffins, danish, do-nuts, rolls, sandwiches, cakes, and breads plus coffee, cappuccinos & expressos.
Hope this helps...have a Great Trip.
