Need improvements. Review on Sherlock's Holmes Pub & Restaurant, Frazer Town, Bangalore

Sherlock holmes pub and restaurant is quite renowned pub cum bar in Frazer town. They were giving couple dinner facilities in Valentine's day. So we booked a table on 14th February evening. The offer was quite lucrative like 1799/-and it included unlimited starter and liquor. So we basically liked the offer. We reached there at 8.30 pm and surprisingly many of its waiters unaware of this offer. They were looking different when we asked about starter and liquor option. Then the manager served our food. I asked for a glass of Coca-Cola and had to wait for 15mins. The waiters were coming and asking for help but unable to serve in time. In main course they had chicken steak and pasta. Chicken steak dish we were unable to eat. The chicken piece was so hard to eat we had only chicken pasts which was good. But because of huge crowd Sherlock pub was unable to serve their customer properly.
