This Madrid-style tavern specializes in Spanish as well as Italian, Lebanese, and Mediterranean tapas. Like many other spots in Barrio Escalante, Olio is known for its lively atmosphere—yet not so lively you can’t carry on a conversation. Its exposed-brick walls and eclectic decor lend it a particular warmth. The restaurant is also famed for cocktails, European wines, and fusion sangrias in locally inspired flavors like pineapple or watermelon.
