What flavor does your husband like for cake? Chocolate, vanilla, red velvet, etc?
How many people will be in attendance? What's your budget?
Momofuku Milk Bar's cakes are good but definitely on the sweeter side and they underestimate how many it ll feed. Get a smaller size than they recommend. They are also not standard flavors and some people don't like how they look.
Most of the good bakeries don't deliver, you'd probably need to pick it up yourself.
