We tried Regrub on a Tuesday evening, and it was not busy. The service was sub-par at best: the person taking our order was not pleasant and a little condescending. The seating arrangements were unclear and we were denied a spot outside on the patio. Server clearly did not have a sense of urgency as our order was waiting on the counter (which we wanted to just grab ourselves). We finally received our beverages and waters when at the end of our meal.
The onion rings were great and the burger itself would have been quite good if the bun was warmer. The fries in the asiago fries were brown and were clearly fried in old oil- still good and edible, just not visibly appealing. Don't ever need to come back.
