We have visited TAO for a number of years.
Unfortunately it has got worse, I say this with a heavy heart since I really enjoyed visiting.
When I first visited there was a very large range of vegetarian dishes and some of the soy really appeared like meat. We had to ask if it was really.
We just 2 days ago and we were confronted by the sign that they now serve meat dishes. Although there is a little segregation the fact it is buffet only means people tend to hover meat ladden dishes over the vegetarian selection!
The vegetarian section is very limited now, there was no fried sea weed and the tofu range has dropped to 6 hot dishes with rice and noodles adjacent to the meet section.
There was a range of diced vegetables but some looked limp.
I went for some chicken style tofu initially. It was chewy but at least warm. towards the end of my meal they topped up the dish from a microwave. I though ahh some fresh tofu. Alas it was cold and chewy!
Although the buffet is only £7.90, drinks £1.50 it can be considered very cheap. However the decline in quality does not make this a special night.
Cons: no fresh dishes anymore, greasy + salty, lack of range of food
