Regarding the betting limits, if you come during day or past midnight, there are plenty of $15 tables along with the $25. I have only met 1 blackjack dealer who was incompetent and had a bit of rude attitude but you can always move to another table.
The cocktail waitresses inside the buffet are friendly and so are the dealers. Third, the service is pretty good overall and most of the blackjack dealers are competent and professional. On Saturday evening, the place is packed everywhere. If you come during the day on weekdays, it is also a pleasant experience in terms of the amount of people. I have been here during past midnight/early morning and there it is a very enjoyable experience with a lot less people.
Second, if you want to avoid the crowds, do not come on the weekends and only come on the weekdays. I don't know how people could have any negative experience or interaction with them since almost none is required. Simply give them your ID, they look at it/scan it, and that's it. I have never experienced any trouble with the personnel who checks your ID.
That means certain restaurants like the casino buffet is accessible to adults 21 & over. First off, this place cards you every time you walk into the casino. I waited to write this review until I went a few times on different days and different times to get a comprehensive experience.
