There has been a TV series about Belgian beers here in Holland recently and they went to the Brooklyn brewery in New York, (its in the bottled beer list). The Belgians visiting thought some of the US beers were very good. If you fancy something different I'd give those a go. The US micro breweries make some good beers these days. Might make an interesting diversion for an afternoon away from UK brews (not for one moment that I'm suggesting that there is anything wrong with UK brews).
Enjoy your time there, lucky you!
