Lux is superb. Best quiche I've ever had! Get there early though, as it sells out quickly. All the bakery items are quite good actually.
The coffee is fantastic - fresh ground, freshly roasted beans are surpassed only by the delectable espresso-laced whipped cream if you are in the mood for something fancy. Try it on a cappuccino or just get a glob on the side. You'll be addicted in no time.
The made-to-order food is also delicious - great place for eggs. To top it off, you can come back in the evening for a drink - there's a small bar that makes really memorable craft cocktails!
