Been there a couple times now, it's OK - big and modern, but certainly not cozy or super unique. Still, worth seeing.
Went to Lagerhaus 95 (Cobblestone district, not far from Harborcenter) and enjoyed it. I feel like Pearl Street Grill is overrated. Also had a few drinks and some food at Pizza Plant in the Courtyard Marriott down in that area too, wasn't bad at all!
All time classics include: The Bar Bill, Duffs, Ted's, Mighty Taco, and if you want to go high end I highly recommend Lambardo Ristorante!
