Oh, I should say this now, cause I'm not sure everyone quite understands...
Do *NOT* bring any food into my house. This is an odd request, but bare with me:
My mother is big on being Kosher. Therefor, rather than trying to explain what you can and cannot bring, it'd just be easier to say "Don't bring any food into the house." So yeah, if you wrap anything up from a Restaurant, bring it back to your hotel room...or just don't wrap it up at all. Don't buy any sort of food unless you plan on eating it on the spot or outside of my house. My parents are pretty strict on this stuff.
I'd love to explain what "Kosher" means but that gets complicated, so yeah, just for one last point, do NOT bring any food.
Drinks are fine, mind (though please keep them non-Alcholic, for all that I don't think that'll be a problem), since Kosher doesn't really apply there.
I don't think any of the above will be a problem; yes, I will make sure there's food provided at my house, but yeah, this is something I think should be noted.
