The common factor.....?

                         
                       What does this establishment --

                       and this public house have in common?

First, some of the differences:

Humpy's is in Anchorage, Alaska.

The Dolphin is in Plymouth, Devon.

Humpy's serves over fifty beers on tap.

The Dolphin serves one, Bass (Ok, they have added some but they do not really count. This is my blog after all).

Humpy's beers are served from taps.

The Dolphin's Bass comes straight from the barrel. (They hide them to confuse the casual observer).

What is the common factor?

A bloody good time.

Visit one if you get the chance, both is even better. Perhaps that is why the Great God of Beer put them so far apart - to visit one straight after the other would be too much fun for any human.
