Review for Viva! Casino Sofia Review For Viva! Casino Sofia Google User May 30 '18 at 8:31 We went here on a Sunday afternoon and were the only ones in the casino outside of a couple playing roulette and one patron at the slots. While i prefer playing blackjack with others at the table, the perks of being the only one were nice as well. Drink arrived quickly. The staff was quite friendly and in a good mood which was contagious. Overall it is a small casino (need to get vegas out of my head), had a nice time and will defenetelly come back when it's more busy. View full site to comment or like
