A great dining experience all the way around. Now I did go for lunch on a Saturday vs. try to brave a late-night crowd when there was a performance; all the previous reviews that expressed concerns about food and service were sooo unfounded. I love the hull-like table I was seated at in the true beach theme...really neat.
Had the beer-steamed shrimp, caesars salad, and cheeseburger in paradise. All just totally hit the spot (the shrimp because it was unique for Vegas, i.e. not on buffet and steamed with beer and old bay spice...the salad because it was gigantic for a small salad and you tend to forgot the "good" food when in Vegas...and the burger, because well, that "is" Buffett's and it was one of the best burgers I've had in a long time).
Beyond that the vibe was very upbeat, Buffett-like for sure. My server was repeatedly refilling my soft drink and water, was very cordial (I was dining alone and using a Groupon), and the food came out quite prompt. In general, the vibe of the other employees was great -- ie when folks are smiling, their non-verbal body language reflects that they're having fun...well that means a very positive dining experience for us customers.
