Have you checked out Blue in Bethlehem? A bit pricey(!), but awesome. No, I haven't! I'll have to check it out, thanks. One of our favorites in that area is the Marblehead Grill (well, it's more Easton than Bethlehem)
Six Flags is cool but its always so packed. I miss Dorney Park - haven't been there in 20 years. I'm sure its changed a lot. Time flies ... Dorney has changed quite a bit. New rides, and it's cleaner than it was 20 years ago.
