One of the best meals I had in Poland was at Stary Dom. They serve traditional Polish dishes like the breaded and fried pork chop and pierogi. The interiors are very rustic and cozy.
Address: Stary Dom, Pulawska, Warsaw, Poland
U Kucharzy is a lovely restaurant serving traditional Polish dishes with a modern twist. It's a very lovely and pleasant restaurant with great atmosphere. It's formal but informal at the same time which is nice as it would work for various occasions.
Address: U Kucharzy, Dluga, Warsaw, Poland
Nice cakes and small bites in this lovely early 1900's Viennese style coffee shop. Another reason to visit is it is in a beautiful hotel which was built in 1901 and survived WWII so the original architecture is still relatively intact.
Address: Cafe Bristol, Krakowskie Przedmiescie, Warsaw, Poland
They had delicious ice cream at the very beautiful ice cream parlour, Lourse Warszawa, in the Raffles hotel. It's actually a patisserie so you can have pastries and cakes too but I was lured in by the ice cream and the beautiful design.
Address: Lourse Warszawa, Krakowskie Przedmiescie, Warsaw, Poland
