We had reservations, as first time guests; WAITING FOR 30-45 MINUTES; WHEN WE WHEN A TABLE BECAME AVAILABLE, PLACE OUR FOOD ORDER WITH SERVER; WAS TOLD THAT COOKS HAD RANNED OUT OF FOOD.
THERE REASON WAS THEY HAD A LARGE PARTY, HOW DO RESTAURANT COOK UP ALL THE FOOD, BUT STILL HAVE CUSTOMERS WHO HAVE BEEN WAITING AND CUSTOMERS STILL COMING INTO THE RESTAURANT, DIDN'T NOT OFFERS WERE MADE TO ACCOMMODATE THE 45 MINUTES WAITING, MANAGEMENT KNEW ABOUT THE ISSUE, NO APOLOGY.
THE LADY BATHROOM HAD DIRTY TOILET PAPER AND PAPER TOWELS ALL OVER THE BATHROOM; FLOOR OF BATHROOM WAS FILTHY DIRTY, THE EMPLOYEES WALKING PASS BY YOU; LOOKING IN YOUR FACE AND DON'T EVEN SPEAK(WAIT STAFF).
QUESTION HOW DO ANY RESTAURANT RUN OUT OF FOOD AND STILL, ALLOWING CUSTOMERS TO BE COMING AS VERBALLY TOLD TO OUR PARTY.
