I visited today and as a business class pax on Turkish Airlines was told that I could only get into the Plaza Premier First class lounge if I paid the $45 upgrade. A shower was like $34 (I did not do that).

I'm in the lounge now as a business class redemption passenger on Turkish Airlines. They only granted entry into the regular Plaza Premium lounge and NOT the Plaza Premium First lounge. I went back to ask and they said that Turkish airlines passengers only have access to the regular lounge and could pay for the "First" lounge. The regular lounge has no showers but for something like $34 or $36 we could pay for a shower.

I found the lounge vibe and Aesthetic to be very premium and high end. The food display and offerings appeared similarly appealing and high end but some of the food was disappointing. The Asado Chicken dish was mostly potatoes. Also, only base line alcohol and most mixed drinks etc. had a listed charge on par with any bar.

Also, the bathrooms I visited weren't really any better than in the terminal. Soap that was out with the filler cannister loose next to it, a sticky and dirty floor, trash can overflowing with dirty paper towels, etc.

Still, it was good enough for us to decide to stay put rather than join the Centurion lounge waitlist and move to the sure-to-be crowded Centurion lounge. Even though they were telling priority pass passengers that there was a waitlist to get in we got in right away (as Turkish Airlines business class pax) even though it was over 3 hours before departure. Once we got in it definitely did not feel crowded and the VERY friendly bar tender told me it hasn't been very busy or crowded in the month since opening.
