Met a friend for drinks at Blackfinn prior to Bruno Mars concert at Spectrum Center. As expected, it was PACKED! We found a spot at the upstairs bar, and had to wait just a few extra minutes to get a drink ordered. It was generally longer than I'd like to wait to be served, but considering the timing right before a 20,000 person event, it was reasonable. Our bartender was fine - not rude but not especially friendly. Beer and martini were good. Ordered fried deviled eggs and fried chicken sliders to eat. The eggs were pretty disappointing. They were fried to perfection, but very bland. I love a deviled egg, but these lacked lustre for sure. The fried chicken sliders were fantastic. Very fresh and tasty. The food did take FOREVER to come out - like maybe an hour. Again, we should expect some service delays during a hyper-busy time, but this was pretty bad. I would probably give this place another try on a night with no event if we lived nearby.
