When making recommendations to customers who ask what is recommended, there are four options: recommend a personal favorite, what is popular, what the kitchen wants promoted, or ask questions to determine preferences. When recommending, it is important to be honest, not rush, allow time for decisions, and tailor recommendations to the customer. Gueridon service can promote menu items through suggestive phrases, point-of-sale materials, attractive trolleys, and referring to advertising. Gueridon procedures involve both preparation and presentation activities in front of customers.
