I see them the same way I do a flask. I think they look cool.....but I don't have a use for them.
The only time I can see using a flask would be camping. A travel bar I suppose I could use at a picnic......but I can't think of any other situation.
When traveling with friends or colleagues, I enjoy finding a cool bar. That is how I discovered The Redhead Bar in Chicago. We just got in a cab asked him for a great old school piano bar. He nailed it.
A good sign of a good hotel is their bar.
That is one of the deciding factors in choosing accommodations. I have favorite hotels in London, Portland, New York, Dublin, Orlando, Vancouver, Torronto, Tokyo, Soul or most places I travel.
Hmmmm.....that gives an idea for another thread.
Sorry I wasn't any help on this one Brad.
