Oh, yes, it's worth it! My family visited TRU Times Square a couple of years ago, and we all had a blast.
For me, it was Johnny Lightning heaven. Peg after peg of JL's--hundreds of them. Nearly every Holiday Lightning for that year was on display and each was 6 deep. I had to behave myself, as it was our first day visiting the Big Apple, and I needed to save room in the suitcase for other NYC souvenirs!
I hope the ferris wheel, T-Rex and the Lego displays are still there for you to see.
OK finally got there, only place I've seen more diecast is the Warehouse sale and the LC store. Didn't buy anything, nothing I don't have or wanted. The HWs were even more impressive, several racks of those.
Went there a few times but on my second to last trip walked out with 17 wl's and three brand x TH plus others all in all a good morning. But that was about a year ago and have not since been back since my accident.
Sounds like a really cool place. I was up that way a few years back and didn't even think about looking it up, wish I would have now. But I did make it over to the street lined with guitar shops, it was cool to see all of the nice guitars.
