Chef-made syrups in your booze

Food Network star-backed B-Side BBQ just scored a full liquor license, which means a ton of sippable bourbon, plus mason jarred cocktails like the namesake B-Side (w/ Kentucky whiskey, mezcal, rhubarb liqueur, and burlesque bitters), and the West Side Julep (w/ rye and housemade minted brown sugar syrup), so... jet over and order one right away?
