Boulder has some great sushi including Happa and Sushi Zamai. Sushi Tora was always the top dog in my opinion but has gone through some ownership changes and the food and service was a little rocky but I am here to say that they are back on track! Went there last week and the food was excellent. The place was packed and the service and atmosphere were great. Plus it is on the West End of Pearl Street which is one of my favorite areas of town. Check it out!
