When I go to a restaurant that has what seems to be nothing grilled and everything in cream sauces, I tend to order pizza margherita, which is the plainest pizza there is, and also my favorite kind . Anyway, I don't know if I'm estimating calories correctly. I tend to only eat 2 slices, which sometimes takes a lot of self control LOL
I like brick oven like Bertucci's and even one from a local restaurant, but it's a 16 inch pizza, while the one from Bertucci's is an individual one. I eat half the individual one, and 2 slices of the 16 inch one. I'd rather overestimate calories than underestimate. Would you assume that that quantity of pizza maybe has around 700 calories? What do you think? I hate when chain restaurants don't post their nutritional info!

Not sure about that but you might try calorieking to see if you can find a decent comparison.
