The idea is a good one in theory: Make a bowl of food exactly the way you want it, and have fun doing it. In reality, for $14 a plate, I'd rather have a chef who knows what he/she is doing do it for me.
As it turns out, the bowl I made for myself was good, but not great. I'm sure if I went there 10 more times and learned about the various sauces I could do a much better job. But for $14 a try, that's just not going to happen.
