Stopped by here by chance (Fish Market & Open Kitchen was closed!)
Ordered a veggie burger & sweet potato fries. The portion of sweet potato fries was a lot but very delicious! The veggie burger held up very well and overall, it was a great tasting veggie burger. A lot of places fail on putting out a proper veggie burger (one that holds together) and I think GBC has done it well.
But for the price I paid (~$11, combo), I would've just went back to another place for a beef burger. Recently discovered a place called Sequel Catering (which none of my friends know about). That simply TOPS ALL burgers in my opinion. Like other reviewers have said, it's not that much different from burgers at Hero or even South St.
