My wife and I are big Bobby Flay fans.  We watch him on the Food Network all the time.  Who doesn't?  So walking around Ceasar's Palace we thought it would be cool to eat at the Mesa Grill.  It was around brunch time.  We were waiting to be seated but the waitress was on the phone.  So we waited.  After about two minutes she hangs up to tell us that they are closing to get ready for dinner.  So we could not be sitted but come another time.  We couldn't believe the rudeness of the girl.  I would of been totally cool if she just told us they were closed in the beginning instead of having us wait for her to get off the phone and her tone be like \"her shit don't stink\".  Stuck up hostesses are the worst.  Uggg!\nBeing the gluttons of punishment we are, we decide to go again the next day again around lunch time.  I should know by now to never give places a second chance but oh well.  Again there is a \"my shit don't stink\" hostess.  Are they trained to act this way?  It is a hot day so I have been wearing a ballcap around town.  They ask me to take off my hat or sit at the bar.  I pause and decide just go with the flow.  I am on vacation.  No need to ruffle any feathers even though my feathers are a little ruffled.  So I take my ballcap off.\nWe decide to order some drinks and appetizers.  The drinks and appetizers were real good.  Bobby definitely gets a star for each.\nWe also ordered lunch.  My wife a salad and a burger for myself.  My wife's salad is okay.  My wife said that it was something she could make herself.  Nothing spectacular.  My burger was okay too.  Way too much bread for a bun.  Even the waiter said that a lot of people say the same thing.  The meat was also not that flavorful.  I have had better.  We should of stayed with drinks and appetizers.\nOverall experience was a let down.  The hostesses suck ass and need to do a better job.  Seriously, you want that to be the first impression of your business.  The drinks and appetizers were good.  The salad was okay.  The burger was okay.  Not what I expected from a restaurant with Bobby Flays name on it.  Defiinitely plenty room for improvement.
