Just used our second one (like cat64) and I think it was the worst meal we have ever had as a family.
It was supposed to be a nice end to ds3's birthday treat to the zoo. We had pre-booked for 6pm but had to wait until 6.40pm to be seated. Every course took about 30 minutes to arrive, ds2 had to wait even longer for his main course so the rest of us had almost finished. Same thing happened with the desserts. The toilets were revolting and the restaurant was unbelievably hot. We got out just after 9.15pm, dd was crying with tiredness and dh has just gone to bed with a migraine.
It really took the shine off our day out and I will be complaining big time!
