Used to special order birthday cakes from Karsh's, but service and execution is consistently better at Barb's. Prices recently went up - my last custom quarter sheet ran about $70 - but they'll make you a delicious cake that's a work of art or a fun conversation piece.
Not Charm Cty/Ace of Cakes "wow" factor, where money is no object, but these are experienced bakers who care about your satisfaction and who seem to enjoy a good challenge. They'll consult with you, discuss options, take the necessary time to get it right. I've always been pleased with their final interpretations.
