We went into Yates's twice while in London and used Tesco Clubcard Deal Vouchers. The first time we had a meal which considering most of the meals are probably microwaved or reheated the food was really nice and we didn't have to wait long either. On our second visit we were on our way back to Euston before leaving so popped in for breakfast. The breakfasts were huge and the staff told us how to get the best deal. They even allowed us to pay for drinks with our vouchers (when they should just cover the food). We went in the afternoon the first time and morning the second time and had great service. It gets very busy after 5pm and in the evenings you have to queue to get in so if you want to eat there then you'll probably have to wait longer. We would definitely go here again to eat as it is good value for money.
