There are some well known restaurant and club scams in Budapest. The basic rule is that if there is no menu on display, or if someone is touting outside, avoid. Never accept recommendations from pretty ladies/men or taxi drivers, unless a relative of yours! There are hundreds of great places we didn't get to visit...including a fun looking Cuban place (although that was more for the liquid menu). A quick search of the Trip Advisor Top 100 should bring up some awesome choices for your trip. If not, visit a tourist information stand and ask for a booklet, such as a What's On guide where there will be plenty of advertising. We hired an apartment with Wi-Fi, which meant we could research a bit before going out and find directions in a city where English is definitely a world away.
I would love to find out your tips of where to eat in Budapest. Now it's a 'special' place, I can well imagine we will return one day.
