there is a buffet where Cosmo was-called something else not quite as good imo, there is a dodgy one up by the savoy, and the old Chinese experience is also a buffet now (my favourite)
The one next to the Savoy (old Riflemans) and the Chinese Experience are the same owners. Funny how they can't be consistent, down to the staff I suppose.
I use the Abbey Meads Rendezvous and it's OK, but there's still a lot of good Chinese takeaways that don't do delivery.
