I can give a bit more detailed. There's an observation that the quality of food increases east to west. So, the general feel is, in terms of taste, Miles < Shelton < Towers < Warren < West (GSU is debate as a dining hall and it can screw with the east-west view).
I also want to note that the general thinking of BU students and dining is usually loving it as a freshman and then decline to opinions based on the person. Some are reasonable and see that they have become too used to the taste despite how they try to mix it up. Others talk as if it is one of the worst in the country.
Anyways, back to the subject, that view is dying as changes came Towers have bettered themselves. I also noted that Shelton's late night dining have bettered too, I would even say superior to Warren's (except maybe the fries, I don't know how good it is at Shelton at earlier times).
Each dining hall does have a unique feel. Shelton does still retain the hotel feel. The sentiment have changed and there are people who say Tower's food is better than Warren's, though the basement thing does depresses the place a bit. I can't give an opinion of Myles, it been too long, but I heard it is still bad (one person I know commentated that taking a girl to Warren who eats regularly there may equal to a date). Warren is, in general, pretty good, though I never find their stir fry ever attractive (while everywhere else seems pretty good). West is generally hailed as the best.
The general sentiment of the new dining hall is largely the issue of the loss of the in-dorm dining halls. It might be only a block or two for a walk, but it is nice to just go downstairs and there's food right there.
Also, does anyone thinking just building a dining hall with a student center in that parking lot a waste of space? Perhaps I am overestimating the potential of the site, but I think it can hold more than just a dining hall. I'm not sure of what of to think of an east student center.
