Good appetizers, friendly staff, good music selection. There was a live band playing on the Saturday that when we went (Campfire Poets) and they were really good! We didn't know people actually dance here, but quite a few did... especially for certain songs. It was great to watch.
One odd thing (neither good nor bad) I noticed was that the crowd were really mixed. There were biker-looking dudes, middle-aged tourist-types who danced really funny, groups of people in their 20's and 30's, families (with adult kids), and groups of girls who must have been there to pre-drink or something before going clubbing elsewhere.
There was even a guy dressed in white jeans and white tee doing a river-dance to a live cover of a Jane's Addiction song. LOL
The "Unicorn" name doesn't suit this Irish pub, which in itself is rather fitting. :-P
Ooooh, I forgot to add, they have1/2 price apps from 5-7pm which is awesome. Not sure if that's available everyday or what... but it's a great deal.
