Query: A great restaurant in Galway?

Galwegians and Galway fans – can you recommend a really nice restaurant in Galway? I want to buy a voucher for a gift, and would like it to be a genuine treat.  I’m open to suggestions for any type of cuisine as long as the food is reliably lovely.

I’ve asked on Twitter and people have suggested Ard Bia at the Spanish Arch and The White Gables in Moycullen.  What do you think of those two, and do you have any more suggestions?
