Decor: if I liked it and it made sense for the ambiance, I’ll give it 3+. If the lighting was bad 1-2!
Service: attentive, not hurried, I don’t have to fill my own glass 3+. If I have to fill my own glass more than once 1-2.
Value: expensive but not great will get a 1-2. Portion size also plays a roll in this evaluation, but it’s mainly quality of ingredients and price. Normally a 3+ is generally not too expensive and great tastes. However a very expensive place with great food may get a 3+ but it would have had to exceed my expectations as the more I pay the higher they tend to be!
Noise: 1 being very noisy, and 5 being very quiet
