I have had terrific meals at Morimoto in Philly, but none greater than the omakase at Morimoto Asia in late October. It was as good as my dinner prepared by Morimoto himself, years ago.
If you want a truly special meal, I highly recommend booking this special dinner. It earned a place in my personal top 10 lifetime meals...and i've been fortunate enough to have had hundreds of exceptional dinners. Even if you don't book the omakase, I recommend sitting at the upstairs sushi bar. Don't judge their offerings by just looking at the menu posted online!
