I am an Irish blooded boy, so I might be slanted in my opinion. :-)
My girlfriend and I try to eat here, whenever we are in the Tempe area. We love the food and the atmosphere. I tend to eat either the shepherds pie (awesome) or we both each enjoy the Trinity Burger (not on the menu any longer but they will make it for you) which is made with applewood bacon, cheese, BBQ and avocado.
We love dining on the back patio, when the weather is nice, and it offers a great atmosphere and vibe.
Rula Bula is one of our favorite little spots, in Tempe, to go out for a bite and a drink.
Sláinte!!
