I went back to FIRST this week right after the Las Vegas Journal Review food critic gave the place a great review (Food: A). I rated it 5 stars in the past and somehow the place has managed to get better.
The new FIRST review.... http://www.lvrj.com/neon/first-food-bar-menu-offers-both-trendy-fare-traditional-dishes-159985745.html
For me, I think it was the addition of some killer desserts....Monkey Bread and the Dirt Cake. wow!
