I think that cost of said items is more important (to me.) Therefore the winner of this category is Hanoi

You consider cost before quality? Well, i suggest that if you have the money to spend. Forget about the cost and go for quality.

About transportation, i think bangkok a better trasnport system in the sense that you have a variety to chose from. You know what they say about variety? It is the spice of life #smiles

Speaking about accomodation, i havent seen a picture from a bangkok house but from you description and from the picture above, i really di think bangkok would ve better in terms of cost and aesthetics.

On friendliness, ability to walk around and immigration, i think those should come under the second category as food and accomodation are the most important to consider
