Most restaurants offer a choice between a smoking and non-smoking sections.
For what it's worth, eateries within a close proximity of Sesame Place in Langhorne/Fairless Hills might do well to zone a "kids" and "without kids" section.
Long lines ("Fast food? Not really, after the entire family gives their order."), oblivious parents - (who really should pay attention after their child has yawped "Mom" for the 443rd time in a row) and some dissaffected food service workers ("Cheese. Yes, cheese, the lovely orange-yellow square right there.") it can be very frustrating.
After a few weeks some single men might ask for a vasectomy with their Meal Deal.
