birthday cake for 2?
I think you can do better than Wuollet. What area of town are you looking for?
If it were me, I'd order a birthday cake for 10 and just eat off of it for a few days. But if you really only want cake for 2, maybe you should consider Cupcakes? Then you can get whatever flavor you want. And my go to cupcake place is Cupcake on University.
