Nova are great no matter what time of day you're visiting. You never feel rushed there and they have some great food. Be aware that their large bowl of shoestring fries is a meal in itself (or nearly a lunch for two), but if you want something sweet then check out their cabinet and in particular their donuts! They are served with an almost-steampunk-style injector full of tastiness (my favourite is the salted caramel) which you then pick how to inject into a lovely warm donut covered with cinnamon and sugar, whipped cream is served on the side. Not just tasty but fun to eat too. The fact they're smack, bang in the middle of town also makes them a convenient place to visit.
