Great now I'm going to be dreaming about key lime cheesecake until I can get one again.

Key lime cheesecake is so fucking good.

It sounds super good but unless it's an anomaly I'd probably hate it 😭

I always try bites of flavored cheesecake hoping I'll find an exception but I am always severely disappointed

Off the top of my head I can remember trying: chocolate, raspberry, cherry, peanut butter, coffee, salted caramel, coconut, red velvet, and yuzu. Disliked all of them because they all tasted like:
[how good the base cheesecake is] - [how good a cake of this flavor in not cheesecake form would be]

So basically the stronger the flavor the worse it'd be, even though I like all those flavors very much (hence having a list that long before figuring out I just don't like flavored cheesecake)

If by plain you mean with red sauce and mozzarella, agree

If by plain you mean none pizza (without left beef), no! ;)

A "plain" slice of pizza has pepperoni on it, IMO. It's the basic topping of pizza. Comparing plain just cheese pizza is worthless.
