Bar Oliva Cafetería

Bar Oliva Cafetería is a 30-year-old Sant Andreu bar known as the temple of migas, and it stays packed for a reason: it keeps a dish that is practically extinct in Barcelona alive. The vibe is old-school and full-on, with migas as the main event.

Order the migas €6, served with a fried egg in the middle — @topfoodbcn calls them absolutely tremendous, and the plate is the whole point. The fried aubergines with honey are also very good and round out the tapeo. That's the move: migas first, aubergines alongside.

Verdict @topfoodbcn's take is that this is the place keeping migas from disappearing, and the crowd backs it up. In the comments, one local calls it del milloret del barri — the best in the neighbourhood — while another half-jokes about keeping the secret. Go for traditional tapeo, not novelty.
