Just noticing this thread (thanks to the newly formatted landing page).
I feel vaguely annoyed when some people don't post prices (even just a very general range) if it's not "self-evident" (and, yes, I know that what's self-evident for person A is not necessarily going to be self-evident for person B; but if we become relativistic about everything, then what's the point of even participating in a forum, yes?). A restaurant's website can have a menu + prices, but it's still helpful to have information such as, "The two of us ordered 6 dishes, paid $200 total, and were still starving!" or "Each entree is really expensive here but easily feeds 2 moderately hungry people."
I also think I don't get uncomfortable w/ food prices b/c I tend not to be too judgmental of others who blow a lot of $$$ on food b/c I don't feel like it's my place to determine what a good value is for THEM (but their info certainly can help me to decide if I might find it a good/bad value for ME). And I work in a profession where I have to have conversations about $ a lot. But I can certainly understand why it might make other posters uncomfortable.
I'm spotty w/ posting pricing information just b/c I'm in such a rush to put out a review that sometimes I forget. If a place is "pricey" or a "really good value," I generally will post that, I think. I also feel like I'm a regular enough poster that the LA folks know I'm not a relative baller.
