What is a Latvian restaurant anyway? Lido is an institution in Latvia and practically every Estonian and their mother has been to at least one of the locations in Riga at least once. Now you too can see what all the fuss is about. The market concept is pretty simple and the food quite hearty. Just grab a tray, and point at what you want, the prices are all listed and the helpings are rather large. You certainly won't leave Lido hungry.
