The Shaken Cow is a milkshake and treat bar on Vaughan Road, part of a small chain with branches in St Albans and Bishop’s Stortford as well as Harpenden. The menu centres on flavoured milkshakes and smoothies, alongside cookie dough, sweets and hot chocolate, with vegan alternatives available.
It operates as a casual walk-in spot rather than a sit-down restaurant, aimed at takeaway treats. Customers can check current opening times and menu options on the shop’s website.
