OpenTable typically allows users to make reservations up to three months in advance. This means that if you are planning a special occasion or dinner out, you can secure your desired table well in advance for restaurants that participate in the OpenTable platform. However, some restaurants may have different policies regarding the maximum reservation timeframe, so it is a good idea to check the specific restaurant’s availability on the OpenTable website or app. Additionally, popular dining times and special events may have limited availability, so making a reservation as soon as possible is advisable. For the latest information, you may also want to explore the current OpenTable webpage for any updates regarding reservation policies.
