Is the food okay? You can’t expect gourmet selections. But the food quality and presentation will exhibit the kitchen’s care – and that will reflect the nursing home’s more general attitude toward its residents. Serving (“plating” in the restaurant trade vernacular) meals in an attractive way makes for happier diners. Judge the food quality by having a meal or two. The sales staff will probably invite you for a meal without your having to ask.
Finally, visit off-hours (early morning and after dinner). Any differences noted in staff attitudes or facility orderliness from “regular” visiting time?
