Ahh yes your traditional Irish Pub! This is the first bar were I had the pleasure of experiencing the Oatmeal Cookie Cocktail (which they do very well by the way). Most of the Mill Ave. crowd know Rula Bula as a great bar but many forget about it as a lunch or dinner option.
They do a great lunch menu with sandwiches, Shepard's Pie ect. I usually get their French Dip with their house made fries which is almost too much food. Their fries are wonderful, basically sliced potatoes fried until they are golden brown. However, I have friends that swear the Shepard's Pie is the best thing on the menu.
The service can be a little slow as they often get hit with the convention crowd from the Tempe Mission Palms next door. However, it's affordable and just good home-style food.
