Small space dining

We live in a tiny flat (51m2); so, our "dining area" is located in our tiny kitchen which already existed when we bought the place. The previous owner constructed a built in dining table that I wish I could remove it to make the place functional but in this economy remodeling is out of the picture. I'm thinking that I should try to squeeze in some kind of dining seats in the living room as shown in photos below. They look achievable to me

Loving the restaurant atmosphere here

this is nearest to the layout of our flat... but still much bigger than ours !

Hmm..I like this hotel look too
