Watched K3G for the first time - what next?

I stopped watching Bollywood films in '85 (synchronized dancing was becoming a thing and 'they just didn't make them the way they used to'). I'm an old Amitabh & 70s Bollywood fan - my favorites are *Amar, Akbar, Anthony* and *Don* and *Shaan*. I recently met a gori who surprised me by saying her favorite film was *Kabhi Kushi Kabhie Gham*, which I promptly watched and freakin LOVED. As a kid I refused to watch movies without any *dishoom dishoom* but I got totally sucked into K3G, loved the songs and the dances. Also: Kajol is 100% my favorite actress. I forgot how much I enjoyed the movies and I have a lot of catching up to do. What do y'all recommend? I assume Dilwale Dulhania Le Jayenge is a must (that's the last movie I can name, I remember everyone talking about it in the 90s). What else?
