I have had multiple meals at Wicked Spoon (dinner I believe is my favorite) and had what I think was brunch or dinner at Bachannal. All meals were good. Can't remember the prices but I had food comps at Cosmo for WS and CLV treated at Bachannal but prices weren't modest at either.
Would recommend both but the lines at both can be long. If anyone is Diamond in your party there will still be a line but it will be a lot shorter at Bachannal.
I have seen very long lines at Wicked Spoon as well but I'll disclose a little known secret that I hope will stay with my fellow LVAers. I am Gold at Cosmo, which I earned but is also automatic (I believe) if you are Diamond with CET. There's a special line for Platinum at Cosmo (Platinum is higher than Gold) but when I first checked in a couple of trips ago I got from the players club (Identity club) or check in desk (can't remember) a little packet with two small cards showing the benefits of Gold and Platinum. Under Gold benefits it says "Priority access to Wicked Spoon."
When I was in Vegas for Thanksgiving I decided to use my food comp to eat at WS for Thanksgiving Dinner. The line was off the chart; 2 hour waits to pay and then be seated. No one was in the line that was marked Priority Access. It might have said Platinum actually. I got in that line and the person said Platinum only. I told him Gold had priority access as well and he said to me if I had something to show that he would honor it. Rules person that I am I had the card on me, he took a quick look (he had never seen it before and I believe he had no idea of this Gold benefit), and quickly escorted me to the cashier. He was quite nice about it. I was seated in about 3 minutes.
There were probably a lot of Gold members in the 2 hour line but who were unaware that the priority access is a benefit to which they were entitled. Members should have the benefits card on them, however, that clearly refers to priority access, which, in my view, is one of the best benefits of being Gold at Cosmopolitan as I do like the WS buffet.
