People say this is the best Hungarian restaurant in London (I'm not sure how many there are) and whether or not this is the case it's certainly worth a try. The menu is all Hungarian and national products also front the wine list, although they pander to the nervous by offering more familiar stuff as well. The food is unusual if you're not familiar with the Hungarian cuisine, paprika features a lot, there is goulash of course and the crisp roast duck is excellent. For the adventurous there's a cold sour cherry starter, and on a recent visit my starter was a chicken pancake which was tasty and nicely prepared. Others in our party raved about a spicy sausage starter, which came with a powerful horseradish sauce. We had slightly slow service for the drinks at a time when it wasn't particularly busy, but this could have been a one-off.
This is a very long-established restaurant, and it was a favourite with the Old Labour crowd, sketches of whom fill the walls. It clearly remains very popular with locals. A good atmosphere.
