sounds good to me, as long as you bring a friend of yours as well. a guy and two girls might just be weird, but two guys and two girls could be a double date situation and might make it more comfortable for everyone involved to have that friend there. just a suggestion...
as for the location, girls like the mall so i don't see her having an issue with going there again lol, especially if she'll have a friend of hers there with her. the whole laser tag thing sounds like fun
