The shakes here are absolutely amazing. To date, my favourite has to be the apple pie shake followed closely by the jittery cow. The Salted Caramel and Vanilla shakes can also make very nice summer time treats. When you stop by you'll likely discover some kind of seasonal shake on the menu (e.g. the Pumpkin shake in October) so the menu is always a little different from what is posted on their website.
In short, if you're in the beaches and want the best shakes you can get, come to Shakes and Franks!
