Traditional Hungarian cuisine tends to be dominated by soup and meat. This is a reflection of the country’s nomadic past (goulash means herdsman, named after the people who used to eat it) and close history with its neighbors. Hungarian food is based on the French culinary traditions with Austrian (schnitzel), Ottoman/Balkan (stuffed cabbage), and Transylvanian (kürtőskalács) influences.
Bear in mind, as you screen for seafood on the menu, that Hungary is a landlocked country. It does not mean that you can't find outstanding grilled shrimp cocktails these days, but dishes with freshwater fish, like common carp, catfish, or perch, are more prevalent.
If you'd like to try the best of traditional, old-school Hungarian cooking, then Café Kör, Menza, or Belvárosi Disznótoros is your spot.
Over the last five years nothing short of a gastronomical revolution has been initiated in Hungary, particularly in Budapest. Although we still love goulash and chicken paprikash, healthier food and smaller portions are becoming more widespread. "New-wave" restaurants generally blend traditional flavors with contemporary international culinary techniques, using fresh local ingredients which were once impossible to find but are now more readily available. To experience the best of modern Hungarian cuisine, try Borkonyha, Olimpia, or Zeller Bistro.
4 Michelin-starred restaurants operate in Budapest (more than in each of Prague and Warsaw). If you fancy such a decorated establishment, the ones in Budapest will likely be among the most wallet-friendly options. My favorites are Borkonyha and Costes Downtown because of the relatively laid-back atmosphere, but the other two (Costes and Onyx) each offer their own unique gastronomic experience as well. Additionally, Budapest has 3 restaurants with Bib Gourmands, a Michelin award provided for exceptional food at moderate prices: Petrus, Laci! Konyha!, and Fricska Gastropub.
As for Gault Millau, in 2017 they rated a total of 15 restaurants in Budapest with 15 points or above.
Italians have their osterias, the French their brasseries. In Hungary, no-frills eateries whose main purpose is to fill your stomach with familiar flavors at affordable prices are called "étkezde". They belong to a bygone communist era, and many trendy people avoid them like the plague. Nevertheless, a few of the best étkezde have managed to survive amid a stampede of new restaurant openings.
To evoke the experience of dining in socialist Hungary, Kádár Étkezde, Városház Snack, and Öcsi étkezde each retain the atmosphere and general food offerings of that epoch. If you'd like to continue along this theme with drinks, visit Bambi Eszpresszó, or, for adventure seekers, go to Wichmann or Villányi Borozó.
The international food scene in Budapest is dominated by cheap, low-quality gyro joints. The expansion of these self-service/take-out type of eateries across the city appears to be unstoppable, but you will do yourself a favor by not visiting any of these (the notable exception being Gyros Kerkyra).
On the higher end of the international food scene, there's a growing group of restaurants which work to meet the standards of serious gastronomes. Italian places are most prevalent (my favorites are Pomo D'oro, Al Dente, and Krizia), followed by Japanese (Komachi), Vietnamese (Dang Muoi, Hanoi Pho), Thai (Tom Yum, Bangkok Thai), Slavic/Balkan (Montenegrói Gurman, PolaPola), Spanish (Padron), and Indian (Indigo, Shalimar) flavors.
The Chinese gastro scene is deceiving because the city is full of uninviting but economical buffet-style Chinese restaurants. These places offer prix fixe lunches of questionable sanitary conditions for the equivalent of €2. Ironically, the food at these places is often adjusted to meet local preferences by adding hot paprika to the flavoring. There do exist, however, exceptional Chinese restaurants located in unexpected parts of the city, including Wang Mester Kínai Konyhája, and Taiwan Étterem.
Just recently there was a conspicuous absence of unpretentious cafés, restaurants, and bars with inviting interiors and quality food in Budapest. In the past 5-10 years this has begun to change. A number of new places have opened to fill this void, and many of which you can find reviewed on this site. While they're a positive and welcome change, I often wish their aesthetics would have more character and reflect our local environment rather than resembling places in other parts of the world. My favorites that stand out as truly authentic and unique to Budapest include Jedermann, Kisüzem, Café Kör, Belvárosi Disznótoros, and Brody Studios.
Food trucks and carts have steadily begun to emerge on the streets of Budapest. Being clean, using quality ingredients, and taking their time to prepare the food, they tend to be a bit more upscale than one may have previously experienced, but aren't meaningfully cheaper than regular restaurants.
The upper deck of the Hold Street market hall features a plethora of options for a tasty lunch. I recommend particularly Séf utcája and Buja Disznó(k). These eateries are run in a self-service manner by some of the notable chefs in Budapest (e.g. Lajos Bíró). Additionally, the market hall itself, a recently renovated 19th century steel structure erected during the "glorious days of the Austro-Hungarian Empire", is worth a visit.
For those unable to rid themselves of the urge to visit a fast food chain while here, make sure it's the McDonald's located inside the stately 19th century train station built by the Eiffel Company - yepp, the same Eiffel who built the tower. Little of the marble pilasters, oversized windows, and ornate ceiling decorations will evoke the experience that's normally associated with cheeseburgers and french fries.
