3 days in Sofia — Tips, food, hidden gems, and general advice?

Zdravo everyone!

We’ll be spending 3 weekdays in the city centre. Apart from general recommendations, any info will be super helpful and really appreciated!

• Any good-rate places to exchange some money?
• Cultural things we should know, or general tips for visitors? How does public transport and taxis work?
• What are some must-try Bulgarian foods? (both restaurant dishes and supermarket finds!). And specific places you'd recommend?
• Anything we absolutely shouldn’t miss — hidden gems or local favorites? Also any cool shops or unique spots.
• We're curious about getting a feel for the nightlife too — maybe not a club, but a fun lively bar would be perfect.

Around what time does it get dark in the second half of November? And when do usually places close for the day?

Lastly, any nearby towns or villages worth visiting as a short trip from Sofia?

Mnogo ti blagodarya in advance for any tips or local insight! 🙌
