Pizza/pasta in Katanga Canyon gets my vote as a good place to eat. The foods simple, but it's good and there's plenty of it.Importantly, the tables are also clean and not sticky! I went there yesterday with 6 friends and the waitress asked if any of us had a MAP - I did so we all got a discount ^^ I'm glad that she asked because I always feel awkward asking for a discount; it's much better when it's offered.
Worst place for me so far has been the courtyard BBQ. I didn't enjoy the meal, but I suspect that was more to do with the weather as it was February and snowing!
I have a general grumble about the coffee shops at AT unfortunately. None of them appear to have soya milk or lactose free milk. Yesterday I was informed at the Towers Street café "We don't do soya milk." To me that seems a bit off hand about what is a genuine dietary requirement for a lot of people and secondly Eurest, who provide the cafés at AT and TP, also provide the café at my work where they quite definitely provide soya milk. Admittedly the café at work did try and charge extra for it at one point, but that was quickly abandoned.
