A tranquil and stately "butterfly" has been calling the Niles area of Fremont home for over 20 years. Perched on Mission Boulevard just west of the entrance to Niles Canyon, near the Sullivan Underpass, Papillon - the French name for Butterfly - has been quietly serving lunch and dinner patrons from near and far with elegance and panache. Fine dining and attention to customer service are not just words here. Diners are welcomed graciously and seated in either the traditional style dining room, tastefully decorated with muted tones or the atrium that glows softly in the evening or allows filtered sunlight through an ivy covered glass solarium for the lunch crowd. Groups can take advantage of a spacious banquet room seating up to 70 shares the fine dining and service of the restaurant. Gentle attention to detail by wait staff means that visitors are seated quickly and white table cloths are neat and ready, garnished with fresh flowers and sparkling silverware. Whether on a tight schedule or dining out in leisure, there is an unmistakable undercurrent of efficiency without pressure. The attentive staff seems to know when diners require attention and are otherwise invisible. The rule here is that customers are the primary focus of attention and they deserve the best from the time they enter and receive a courteous greeting until they depart satisfied with a pleasant wave farewell.
