The cave in BATMAN RETURNS was small?

His workstations, maybe.
And that's just the lower level.
The thing about BATMAN FOREVER one liners...
Some of them actually had meaning. Batman didn't just say these things for the hell of it. They were jokes, but they weren't just jokes, and Kilmer sold them wonderfully, and they set up other lines from Chase. The character was actually trying to diffuse an uncomfortable situation with humor here, it wasn't a case of making the audience more comfortable .
"I'll get drive thru" is a little cheesy, but it was also a clear attempt to show that he'd lightened up from the get go, but not completely. That he was comfortable enough in his mission to rib Alfred about his habits.
And I'll always love "Holey metal ground, Batman!"
