locationlocationlocation: accesibility, alot of buses/mrt pass, no need walk far. near main road. if oh high floor in buildings make sure have lifts/escalator.
price: reasonable, doesnt have to be cheap. suited to other factors
opening hours: hmm...i bet nobody wants to jam at 7am? 10am to 12pm maybe. last booking at 11pm? only suggestions. see ur business how.
