I've used Curds and Whey several times for office functions and for private parties. Great food and very easy to work with. They are just off the Fairway, behind Jenkintown Barnes and Noble - same shopping center as Jules' Thin Crust.
Here are two more choices Joshua's right in Jenkintown very good for and service. http://www.joshuasevents.com/ Also All ways cafe excellent food for a luncheon The pharmaceutical reps do tons of lunch catering from here http://www.allwayscafe.com/ Can't go wrong with either one. Curt
