We do not understand why Lago has such negative reviews - it is our favorite buffet, and we have done several.  Sure, it does not have as much variety as other casinos such as Planet Hollywood or Paris... the quality, however, is much better.  The meats are cooked better than most buffets, and the fresh fruit is usually much better.  We love their sugar-free desert options. Every time we go to Vegas, we look forward to eating at Lago.
