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!
