open-table-widget

The Pro version works great and the support guys helped me out when I was having a problem with the datepicker showing up when I used the widget in a popup. My client will love this! Update: Plugin no longer works in popup. Support request went unanswered.

The Pro version is well worth the support they provide you. We had an issue regarding HTTPS and they were prompt to email us as soon as they fixed the issue. The plugin itself is better than Open Table's widget

Just compare this to the official widget from OpenTable. The official OT widget comes with 2 designs, horizontal and vertical. This widget comes with more options, modern and simplified design. It's also much easier to apply CSS styles to if you want to make sure it matches your website completely.
