Shake Shack offers two similar milkshakes: the 'vanilla and chocolate shake' has both custards mixed, whereas the 'black and white shake' features vanilla custard with fudge.
Shake Shack opens its fourth South Bay location near eBay, transforming a former Boston Market into a vibrant space with ample seating for 140. The new location features a modern design and a variety of menu items, including seasonal milkshakes and gourmet burgers, while also supporting the local community through charitable donations.
