I need to buy some new diner tables, do you know any?
I would suggest IKEA. They are the best and you can modify them as per your taste, they have different themes, tables, chairs, stools, decoration rugs, inclusive of everything.
Can you order online?
Yes they do have an shopping app for online users.
Do you work for IKEA? My wife wants to shop around but I am so broke
No I dont work for IKEA. 
I love the wooden tables that have that thing you can spin around in the middle so when your family eats, you can share the experience of foods. Do you like this too?
As far as I know, it should well crafted and it should fit well the room size. I suggest you can pick up from Mahogany, walnut or composite woods. based on your budget.
I like the type of wood that is glazed and looks really old like the lord of the rings hobbit type of scenery wood!!!
Oh, I think they are expensive.
