O Burrito
As you're heading past Sé Nova, take the first alley on the left to discover this tiny bohemian spot tucked behind a church. The Mexican fusion restaurant has a small but delicious range of hot and cold vegan empanadas, quesadillas, and massive burritos. The quirky setting, with mismatched tables and chairs and board games scattered about, is a popular hangout for local students. No international cards are accepted, so be sure to bring cash.
