The menu constantly changes at Mr. Bartley’s - not because it’s a seasonal place that tells you the name of the farmer that picked your kale, but because the burgers at this greasy spoon place are given jokey topical names that mock right wing political figures. So if you’re looking for a throwback to the dirty, quirky Harvard Square of the ’70s - or if you only eat burgers named after Brexit supporters - this is your place. Our current favorite is the Government Shutdown, which comes with jalapeno and hot sauce.
