A little horseradish in your beet salad?
This is a great place that has hearty, satisfying, tasty food. If you aren't familiar with Hungarian (and I'm no expert) I would definitely try it. It is not what I would call challenging - most people will find things they like and it is different enough and excellently done.
On a couple different occasions I've tried several great dishes:
Beet Salad and Cucumber Salads are both fresh and great.
Their soups are amazing. It's tough to get one because their portions are so big, but they are well worth it - get one as part of a meal sharing plan!
Their Hungarian Lecso is a flavorful, hearty (this word will get used alot) and filling stew with sausage.
Their Schnitzel is famous for good reason, and I totally agree with the recommendations of squeezing lemon on top, generously.
Also have enjoyed their Stuffed Cabbages (not quite as good as grandma's, but good) and Paprikash (including Mushroom, which is vegetarian).
My wife asked for gluten-free options and was given several. The server was conscientious about suggesting things she could eat and even checked the ingredients on the dressing for the salads (luckily gluten-free).
I also enjoyed the Sour Cherry juice (not very sour) and tried a Hungarian white wine, which was nice.
I'll also echo the comments about portion size. The larges are easily shared and the smalls will not be finished by many.
I loved the food in Hungary on one trip, and this definitely reinforces the goodness.
