There are milkshakes, and then there are boozy milkshakes. You can have both at The Hourly Oyster House in Harvard Square. If you’ve got a bit of a sweet tooth and a fondness for ice cream, get over to Cambridge to check out their rotating selection of milkshakes (with and without alcohol). Each month, the restaurant rolls out a new batch of these decadent treats, often along seasonal themes, featuring a variety of liqueurs, candy, cereal, cookies and more. This month’s line-up includes May Flowers with vanilla soft serve, lavender, Becherovka and white rum; Bittersweet Symphony with chocolate soft serve, Santa Teresa Rum and Amaro Angostura; and Malted Milk Ball Milkshake with vanilla soft serve, malted milk balls malt powder. 

Make sure to follow The Hourly’s Instagram for updates each month then book a table for lunch or dinner (and save room for dessert) so you can try them all. Reservations are available online or by calling 617.765.2342.
