Figovec is good. Traditional Slovenian food. Few minutes walk from the IC. https://maps.app.goo.gl/7zB3knsLxkFbFPki7

If you an ambassador, I also recommend going to the hotel restaurant on the top floor 1 night for dinner to use your credit. It's michelin recommended, great views and the food is really good too. Not cheap though (for slovenia), but the credit softens the blow a bit

also don't forget to order the truffle omelet for breakfast!
