Center Valley recs
Melt in the Promenade Shoppes I really enjoy. It is pricey but the service is always excellent. There are people on these boards that do not feel the same as me.
The Glasbern is excellent but it is about a half hour from Center Valley. Some people complain it is only prix fixe on the weekend with more limited choices but the choices are always excellent.
My current recommendation would be Cosmopolitan in downtown Allentown. Free Valet parking gets you past the issue of it being downtown.
If you want to stay in Center Valley and price is not an issue you can go to Shula's or if you prefer Asian, go to Kome and for Thai go to White Orchid.
There are several other great restaurants throughout the Lehigh Valley from Easton through Bethlehem and Allentown and the suburbs beyond.
Yes, PA board may yield more recs. Bolete has been touted as very good, we have found it so on occasion but sadly also very disappointing on other visits. If you visit on a good day you will be please with the food and service and happy to pay the price, which for that area is relatively high. As we have to travel to dine there we have crossed it off our list because of spotty experiences. However, if we are close by we will always give it another try.
