I followed this guys from tiktok, Nikola from @foodandcoffeegbg and found this restaurant
Bistro Giardino at Göteborg City right beside Stads Museum @ Norra Hamngatan.
The food is amazing good! I love the tagliatelle, perfectly cooked and the Entrecôte also perfectly grilled! You must try when you are in the city! You can also do ”fika” here
