I had been at PJ O'Brien's once before on a Thursday evening with a friend. She and I both felt comfortable sitting at the bar. The atmosphere was friendly. I returned on Saturday evening with another girlfriend and we sat at the bar in the upper room. We thoroughly enjoyed the band, Fiddlestix. What a talented group! An earlier comment mentions this band and the type of music they play. It was great to have a few words with the band members when they finished their first set. The other patrons were friendly and strangers were speaking to one another. Many people were dancing. Connor the bartender was great! We enjoyed our nachos...we ordered the regular ones. My friend and I will definitely be back, we had a wonderful time!
