Armenian (Birmenka) is the oldest coffee shop in the city, where you can enjoy coffee made on the sand. My friend and I visited there as many as 3 times in 3 incomplete days. And all because of the very homely atmosphere and pleasant service. Masoch is a legendary place named after Leopold von Sacher-Masoch (he became famous for his "extraordinary" preferences). There, on weekends, they arrange a whole show for visitors, the waiters can whip a whip in the butt or pour ice into the guest's pants. But we got there on a weekday and there was absolutely nothing to do there.
Very Haute Cuisine - to get into this restaurant, you need to go to a communal apartment to one of the sweetest grandpa. With him, you simply have to talk and guess the riddle, then he will let you in.
Kryivka (Kryivka) is my recommendation if you come to Lviv. This is another legendary establishment that is not very easy to find. It is located in the basement and to get there, you need to say the secret "went out" (Glory to Ukraine!). Then mead is poured and allowed inside.
