For the most budget-friendly dining options, you can expect to spend around 45 EUR, which can get you a large hamburger or pizza, for example. Some of the most economical eateries in Amsterdam include Vlaams Friteshuis Vleminckx (where you can enjoy fries and fried foods for 5-6 EUR), Wok & Zo (known for its excellent seafood pasta), and the Frituur chain (be sure to try the local specialty - croquettes filled with cheese or breaded vegetables).
In cafes, the average bill tends to be between 12 and 20 EUR, while in Amsterdam's more affordable restaurants like Haesje Claes or Brasserie FLO, you can expect to pay between 30 and 50 EUR.
