Direct answer
Posada Margherita for the Hotel Zone wood-fired benchmark. Pizza Lo Zio in the Pueblo for thin-crust Italian at local prices. Burrito Amor's pizza nights when they happen. Skip beach-club pizza — overpriced and mediocre.
Tulum's pizza splits the same way the rest of its food does — Hotel Zone (Italian-owned, beautiful settings, expensive) vs. Pueblo (real Italian expats, normal prices). Posada Margherita in the Hotel Zone is the famous wood-fired spot (~$25–35 USD per pie). Pizza Lo Zio in the Pueblo does proper Neapolitan for ~$10–15. Beach-club pizza is universally not worth it.
