hope your trip is meeting your expectations. you seem to have done a good job so far of avoiding the awful stuff on sale in the uk.
(fosters,carling,john smiths, strongbow etc)... if you hanker for a taste of home, a wetherspoons pub will have bengali and resin as well as other beers with U.S. hops.
Wherever you go , the pubs near the coast are still in reach of the “ Press Gang “ so drink with your back to the wall to avoid the Kosh and a glass bottom tankard to avoid the shilling......other than that just get to the Real Ale pubs or look up on the CAMRA website for worthy pubs . Have a great visit and I must say some of the American IPA,s are really good from your side of the pond .
