Underground Cave Movie

I need some help remembering a movie, I know it's a long shot and I can only remember a tiny bit of the ending...but it's been in my head and it wont go till I know what it is!
All I can remember from the ending is as follows ;
There's a bunch of people in like an underground cavern, some beasty monster things are climbing all over rock pillars hunting them, they get out somehow then 2 of the survivors meet at some coffee bar in I think Italy, they think they got them all but I think the girl's eyes change or something.....
That's all I can remember! I know it's probably just some random B movie pile of crap but it's bugging me!
