John Curtas is one of my favorite people writing about Las Vegas. His take on the Vegas food scene is always informative.
Curtas today posted a run down of some of his Encore experiences which are worth a read: http://www.eatinglv.com/2009/02/the-trouble-with-encore/
Now, I am no food critic. I have a fairly unsophisticated palette though I do enjoy food quite a bit. Having eaten at all of the restaurants in the post, while I cannot rebut any of the specifics, I will say that I would put Botero in the list of restaurants at Encore I would look forward to going back to. Both of my meals there were quite good, by my admittedly 'simple' standards.
