I really can't, in good faith, give this place a good review. I've experienced Edo twice now, once for a pick-up lunch special and the other for delivery. The pick-up lunch was okay. I did one of the 2 roll combos and it came with a cup of miso and a small salad. A-Okay.
The delivery order was simply awful. It was super slow to arrive (90 minutes) and nothing was at the correct temperature. The tempura was soggy and not well prepared. The sashimi was warm and incredibly unappetizing. I had one piece and could instantly tell that this fish was previously frozen - and questionably thawed (had a bizarre texture.) I honestly could not see going back for delivery and even going back for take-out is questionable at this time. There are simply too many better options in the Madison area for this to happen.
Ultimately, your time and money are best spent elsewhere.
