Mighty O was a great choice. We had it instead of cake, and the guests, from toddlers to adults, loved the donuts. My mother in law made a donut tower from Pinterest to display them, and it was really pretty and lots of fun. Mighty O delivered the donuts for a small charge, and the total for the donuts and delivery for a 100-person wedding was much less than if we had had cake (and much more delicious, in my opinion!) The customer service was also great. We stopped by the cafe on day on a busy morning and an employee took the time to give us a full tasting. Then, in the chaos before the wedding, I forgot to pay for the order, but they delivered them anyway and just had us call in the credit card information a few days after the wedding. Plus, we took the leftovers back to the hotel where all the guests were staying and everyone had donuts for breakfast the next morning!

We had donuts instead of cake, and it was great! We ordered about 6 dozen full size and 6 dozen mini donuts. Our guests loved it!
We ordered and paid a few weeks in advance. You can order by email, but we just went into one of their stores. They helped us fill out the order form and we were done in 10 minutes. We had one of our bridesmaids pick everything up the day of the wedding, very easy. Our caterer displayed the donuts on some nice serving dishes, but we didn't have to pay a cake cutting fee.

The donuts are delicious (they also happen to be vegan) and we ordered about 7 different flavors. My only complaint is that one of our flavors wasn't available and they subbed something different. It was still delicious, but we weren't notified until we opened the box and saw the substitution - would have been nice to know! If you are considering a cake alternative, I would highly recommend Mighty-O, it was just so easy and the donuts are really good.
