Pair your beer with a bun—for a bargain—at Cambridge Brewing Company. Each Sunday, the Kendall Square restaurant and brewery has a new hot dog on the menu, available for just $3 as an add-on to a liter of suds. The Brewer’s Dog special rotates weekly, but past creations include a Banh Mi Dog (with habanero Sriracha aioli) and a Street Corn Dog (with avocado-garlic cream). Call 617.494.1994 for more info on the featured frank – available for $5 apiece on its own – or head over for the hops and hot dog combo.
