I haven’t read all the comments so sorry if this idea has already been mentioned. Coming from someone who owned a wholesale bakery delivery to local coffee shops: have you thought about collaborating with local bakers (different every day possibly)- they would also share to their followers & being customers in? Also increasing average spend- do you have options for kids? (If they’re coming in). And sandwiches/lunch options possibly?
Seasonal coffee menu that draws people in- fun experimental flavours
