I've eaten here several times and USUALLY have a great experience.  However, the last two times I've visited the ESPN Zone, the service hasn't been that great and the food is on a downward trend.  During my last visit, the nachos we ordered came out barely warm...as if they had been sitting for a few minutes.  Then the burger I had, tasted like cheap beef.  I have eaten a burger here before and I know this was not their normal quality.  Ironically, while I was staying in Vegas, the news reported that Disney will be closing several ESPN Zone restaurants, including the one in Vegas.  If you want to eat a sports bar with lots of tvs, go to Iggy's.
