Golden Orient is a bad example of a type of cuisine (all you can eat Chinese buffet) that you can't expect much from. Therefore really does show quite how bad it is. If that's your cup of tea, go to Buffet Island instead, in Newcastle. There's a place in Lichfield which is the same concept but they bring the order to your table instead - can't recall it's name.. Green Tea maybe or something..
Vivere is an oddity. I went when it first opened and really wasn't good enough, but then my main issue was the menu since I rarely order pizza's in an "Italian" and there wasn't much on it for me and very tomato based sauce heavy (and having been to Italy 3 times recently, not all Italian food is cooked in a shoddy ragu...). I had a steak that was mediocre at best. The second time I went, I ordered a pizza. It was nice, but no better than pizza express tbh. I also ordered a bottle of wine that was just undrinkable. It wasn't corked as far as i could tell, just bad. Very bad. In fairness to the staff, they swapped it for another bottle of something more drinkable (more expensive) and didn't charge me the difference. So good service, potentially good food let down by a poor menu (which is subjective I agree). I will go back. However there is NO WAY it is in the top 50 restaurants in the UK which their advert says on the front.
Back to the original topic, the only Must-East place in Stafford is The Moat House brasserie in my opinion. Although the Holly Bush in Salt and Karma (sad news) could also get a look in, although for different reasons. I've also always been happy with meals at The Sun and The Bear Grill, but would hardly call either Must Eat.
Stafford really needs a Must Eat place.. so much is resting on The Post House's shoulders..
