I'll translate this for you:
Girlspeak: lunch=platonic, dinner=date (this is in general terms, not an absolute rule).
So, if you're asking them to go to lunch, they're assuming it's more likely to be a platonic get together than a date.
If you're asking them to go to dinner, they'll assume it's more likely to be a date than a platonic get together.
Alternatively, depending on how long you've know them and how well they know you, it's also possible that they realise you're asking them on a date, and they like your company and want to be friends, but their response 'who else is coming' is a way of making it clear to you that they want it to be a platonic thing. They're putting you firmly in the 'friendship zone' and letting you know that while they might like you in a platonic way, they're not interested in you romantically.
