Montserrat has the largest concentration of Spanish people in Buenos Aires, so it makes sense that once you walk into Centro Asturiano, you’ll feel like you’re in an old tavern in northern Spain with wine bottles, vintage photos, and antiques everywhere. Come for lunch after you tour the Barolo Palace and Parliament Square, order one of their ridiculously large tortilla españolas, and add on some gambas al ajillo that’s served sizzling in the traditional clay pot. Close out your lunch with a cup of custard.
