Guanghan City is not very big in the first place, having time to go to Dianzhao Restaurant (old shop) and have a dish of authentic Sichuan cuisine for a while, then take a taxi to Sanxinggou for about twenty minutes.
Local features include recommending a small, specialty shop called Little Corner near the Tax Bureau, with scented and cozy atmosphere. The fire pot food is similar to most others, but the snacks are exceptionally good.
