Prague is definitely beautiful and I really enjoyed this trip. However, my credit card was stolen there and the fraud guy spent 3000 euro online in a day... I already canceled the card but it made me have a mix feeling. 

Kutna Hora is a small town one hour away from Prague by train. I would recommend you to check it out if you have some free time. Bone church is what it's famous for but there are more to be explored. I went there on Saturday and it was relatively quiet since some of the shops were closed. 

Trdelník - This is the Bohemian traditional dessert you can easily find on the street. I LOVE it!! So delicious but it's very sweet (since there's tons of sugar on it). Must try if you travel to Prague.
