We had so much fun with our guide Julie. All four bars were well chosen, very classy - these were places we would love to hang out if we were local residents (not touristy), and all cocktails were tasty. The tour operator obviously made arrangements with the bar so we were there relatively early (tour started 5pm) and before the peak hours so it was a bit quiet. We enjoyed the chilled vibe without the crowd when the bartenders were relaxed, attentive and had time for a bit of chat.
The tour was so enjoyable, largely thanks to our wonderful guide Julie. She is warm and engaging, and made our evening memorable.
