Oak on the Pearl Street Mall might just be the top restaurant in Boulder. Excellent food, atmosphere and service. It has it all going on. And they make some wonderful cocktails too. I recently returned and had the Double Cheeseburger with a Fried Egg and Tator Tots. So good. The Porkbelly Ramen is fantastic. Throw in some Fried Pickles and life is good! And now they are open till midnight Thursday thru Saturday.
