I went here for a girlfriends birthday dinner and it was pretty good. Definitely pricey for what you get but pretty decent.
We ordered some oysters to start followed by the burrata, which was pretty good. Nothing to write home about. We also ordered the tuna tartare which was probably the star of the night. It was seasoned well and the soy honey sauce really stood out.
Then for entrees my friends and I shared steak, lobster Mac and cheese, parm truffle fries, cauliflower gratin and the polenta fries. Everything was decently good but there is really nothing I would crave and go back for.
On another note, the ambiance is cool in the Cosmo so it gives the restaurant a nice vibe. Our waiter was nice and attentive to our large group so I have to hand him that. I honestly just didn't think it was worth the exorbitant price we ended up paying for dinner.
