I've never been disappointed at Sterling Bagels. Their bagels are the best in Vegas...big & chewy. I usually ask for mine with easy cream cheese because they are really generous with their portions.
All the sandwiches are excellent because they bake their own bread and use great quality meats. Pastrami is killer here as is their club.
The family loves their breakfast bagels but I'm not crazy about them. Their bagels with smoked salmon is probably the best I've had.
They have a great deli counter and we often bring home egg salad, chicken salad, and pate home.
I know they do big business on Jewish holidays because they sell tons of platters. I've taken platters to customers for their office staff and they've raved about the food.
The only real downside is that it's in Sun City. Navigating that parking lot with all the senior citizen drivers can be hazardous!
