The more the merrier, especially when it comes to margaritas, and the trio of Burro spots — Burro Bar – South End, Burro Bar – Brookline and The Painted Burro — are giving you no shortage of places (or days) to celebrate National Margarita Day. Stop by any of chef-owner Joe Cassinelli’s spots from Friday, February 22nd through Sunday, February 24th for a weekend-long party all about tequila. At each location, they’ll be serving a margarita flight special with two different flavors duking it out. Whichever drink wins will be featured on the menu of all three restaurants beginning on Monday, February 25th — plus, when you do your part to vote for your fave, you’ll get a voucher for a complimentary iced coffee horchata for your next visit.
