Ali Baba has been on its corner of King Hussein Street since the 1960s and is the standard recommendation for Aqaba's grilled fish — the menu is essentially what came in off the boats that morning, charcoal-grilled whole and served with rice, mezze, and a green salad. Sayadiyeh (fish on spiced rice with caramelised onions), kibbeh with shrimp, and the daily catch are the usual order.
The dining room is informal — wooden tables, ceiling fans, a long bar — with a small terrace on the side street that fills first in good weather. Prices are reasonable, alcohol is served (Aqaba's special-zone status), and the staff are friendly to wandering travellers. Open from late morning until late evening; no reservations.
