Phoenix Restaurant is a cafe that I wasn't a big fan of years ago. I remember it being expensive and lacked variety but I went again recently and was impressed by the large selection and decent prices. I had their alfredo with a fluffy pastry at the top which added a great texture, their chicken wings are also freshly fried and very crispy. They also have a good dessert selection with waffles and sesame ice cream as my favourite.
