Have you tried Aroma nearby in Franklin Park? I can't do the old Pad Thai/Thai Basil/Green Curry rotation that my fellow locals seem to like. Aroma does a lot of different stuff, seems like I'm getting something new that I love each time, but I go infrequently enough that I can't fully rule out that it's the same dish and I'm just forgetting it in between visits. Seriously though, menu does seem a lot more varied than other places in NJ.

A lot of the ethnic food near Princeton is Indian, but even at that, I'm not sure there's a standout place - it's just reached pizza-like status that everything's at least acceptable if they're staying in business.
