Are themed cafés in Tokyo actually worth visiting or just a tourist trap?

I have been planning a trip to Tokyo and I keep seeing all these themed cafés and restaurants pop up in travel guides. Everything from character cafés to really wild concept restaurants. Some of them look super fun, but part of me wonders if they are more about the novelty than the actual experience.

I usually enjoy finding quirky local spots when traveling, but I am not sure if these places are something locals actually enjoy or mostly for visitors. Has anyone here tried any themed cafés or restaurants in Tokyo that were genuinely memorable and not just a quick photo opportunity?
