I had dinner at STRATTA, at The Wynn. I ordered truffle fries and a pretty good vegan pizza with caramelized onion and (I am assuming Daiya) vegan cheese.
While I can't complain that there actually were vegan choices, I do wish there were a few more than were available. At least most, if not all, Wynn restaurants offer vegan dishes--and that's more than you can ask for when going to any non-veg establishment.
The food was QUITE expensive and even though I wasn't paying, I did feel a sense of diner's remorse for that reason.
