An Irish pub typically features a traditional wooden bar counter. Oak and mahogany are popular choices for this type of design, as they are strong, durable and have a classic look that fits well with the traditional Irish pub aesthetic.
For a more authentic look, consider using reclaimed wood for your bar counter. This can give your pub an old feel and also adds a unique touch to the establishment.
Additionally, many Irish Pubs have a brass or copper foot rail, which can add to the traditional ambiance and also provide a comfortable place to rest your feet while seated at the bar.
