I agree with your list. I have been to Dublin, Tayto and Belfast. Unfortunately I have not been to Fota wildlife park as it so far away but I have heard it is very good. Dublin is a definite number 1 and the fact it is constantly improving makes it one of the best in the UK. Belfast Zoo I have been to at least 20 times in the last 15 years (since I was 1) and it has not changed bar a new gibbon enclosure. As a result its enclosures have slowly got worse as standards have improved. Dublin has a superb Asian Elephant enclosure which mimics its natural environment while Belfast's is small with metal bars and has no water.
