Cheap Bites Under 5 Euros
Kompressor
Rataskaevu 3
Giant pancakes that will leave you struggling to get out the door, no joke. Its even worth considering to get one to share.
Supermarkets
All supermarkets will have a hot food bar, salad bar and bakery.
For hot food or salad, get a ticket number. When its your turn, tell them what you want and the box size (body language also works).
EAT - Sauna 2
Western style dumplings. With 3 types to choose from, grab a bowl and get however much you want. You pay by the weight. Or order off their menu for other things.
Lido
Various
Buffet style resturant, choose what you want and make your own meal. (Not a all-you-can-eat type buffet).
Because not all of us have the talent for cooking. Fortunately for us, there are quite a few interesting cheap places to eat around Tallinn.
