Last year, I visited KUMU Art Museum in Tallinn, Estonia. There is only one eatery at KUMU Art Museum serving coffee, sandwiches, salads etc. Again, I opted for a croissant with additional ham and cheese. I ordered a caffè latte ( 2.3o Euro) there which was more expensive than in Italy ( Latte Macchiato is approx. 1.30 euro at Dorian @ Turati). I forgot what it was like. It should be ok as I was too hungry to complain !
The best thing in Tallinn, Estonia is free wi-fi in most places and luckily this place offers free wi-fi too!
