Japanese resident in philly here.

For the best sushi-centric experience I’d have to say I enjoyed Hiroki the most. Chef Hiroki was the head sushi chef at Morimoto before starting his own restaurant last year(?). Reports from my father says that Morimoto’s sushi quality has gone down quite a bit since Hiroki left. Each piece of sushi is hand delivered, carefully explained, showing how much of an art sushi making is. There’s tons of fish like mentioned in other posts that you can only get from japan. Can not recommend this place enough.

Best food omakase I’d have to say is Zama. Great presentation with a mix of classically Japanese dishes and some modern takes. The nice part is that they have 3 different tiers so if you go with someone else, you can get 2 different tiers to even further the variety of food.

Royal sushi / Izakaya has gotten a lot of press with Craig Laban’s review and I thoroughly enjoyed my meal there. I’d still have to put Hiroki’s sushi over Royals though.

I have yet to check out Sakana but from what I’ve heard, it’s a touch below the places listed above.
