Hi

in a nutshell: no, this will not work
all the plugin does is allow someone to order for a set timeslot (in 5, 10, 15 min …. etc steps) that is available during your opening hours

i.e when you are closed, it will offer the timeslots available when you are next open (or indeed a few days in advance – depending on settings)

if you are open, it displays the timeslots to choose from (so if you are open 24/7 it will display those up to a given number of days in advance )

unless you have different sites ( one from breakfast items , one for hotfood Wed-Sun etc ) it knows nothing about what you may or may not want to have available for ordering

in a way it’s kind of binary.
if you use it , timeslots during your opening hours – depending on your settings – will become available for a customer to choose from . that is pretty much it . it makes no distinction between any of your products

(Though there is a bit more granular control as to time in advance, preparation times, max orders per timeslot etc etc, but none of this applies to what I understand it is you want to achieve )
