The processor is configured to: receive a request for a reservation including a set of attributes such as a date or date range, a time range, a location, a cuisine, and a party size; determine a set of available reservations based on an actual table availability for the date, time, and the party size; determine one or more offers based on the date, time, and the party size; determine an overlapping subset between the set of available reservations and the one or more offers; and provide an indication of the overlapping subset. The memory is coupled to the processor and is configured to provide the processor with instructions. There are many ways to do that.' highlight(source, 'are to a is in on the of at or an')
