Hi Shawn! 

Budapest is great - we went in April 2014 and loved it. Check out the House of Terror and the Széchenyi Thermal Bath. 

There are a few ruin bars around, which are very cool, but also quite expensive (London prices). Head to the quieter streets and local bars for cheaper options. 

Check my post on things to do and see in Budapest (including some rium bars we liked):

Have lots of fun!
