Celadon and Angele are both excellent, IMHO. Morimoto is pricey for sushi (though not Kenzo expensive), but also excellent, and the space is cool. I’ve been hearing really good things about Charlie Palmer Steakhouse, but haven’t been myself, and Cole’s is also great for meats. Don’t be shy about BYOB.
For a drink/bottle before or after, try Compline, hidden back next to the Archer Hotel. Or, if you like sherry and pintxos for a snack, La Taberna.
If you are wanting some decent cocktails there is a hotel Andaz. The bar on the second floor is pretty good and outdoor which is nice and relaxing. Good vibes
