I went to Costata last night and really enjoyed the dinner. The fatty tuna and red prawn crudos were really phenomenal. Even better than those at Marea, IMHO. Both the rich, well-aged toro with sea salt, and ultra fresh, sweet red prawns with lime scent and olive oil, blew me away.
40-day dry aged bone-in sirloin was full of flavors and tasty.
Even the dessert I had, 'gelato alla meringa', was really good with baked meringue, rhubarb sorbet, strwaberry gelato, and ladyfinger cake. Not overly sweet, just perfect!
The Fourth at Hyatt Union Square was decent, and Betony was really impressive, but among the newly-opened places that I have tried so far, Costata was the best for me. (And the most expensive too, lol)
