The short version
Out in Rosamond, Diamond Jim's works as much as a restaurant as a card room, and a good number of its fans never touch a chip. They come for big plates at low prices, a full bar and regular drink specials. One diner points to the all you can eat taco night on Tuesdays.
The poker is local and low stakes, mostly $1/$2 hold'em played with $1 chips, which slows every pot down. Seats can be hard to get when dealers are short, and two recent visitors waited around two hours without getting into a game. Blackjack gets a rougher review, with a few players feeling the dealer won far too often, and tournament players complain about how the floor handles disputes. It isn't open all night like the LA rooms: doors close at 2 a.m., or 4 a.m. on Friday and Saturday.

I'm from the UK, went for poker. Midweek around 4pm.
$1/$2 table gets filled multiple tables, lovely (min $100 max $200) buy ins.
$2 / $5 (min $500, max $1000) had 4ppl on the list (including myself) didn't get filled mid week. The venue said this is unlikely mid week. (Fair enough)
Good people, good waitress…
We go for there for their restaurant, not the table games. The food is always excellent and the staff is always friendly. Tuesday night is all you can eat tacos for only $9.95/person with $5 margaritas. Can’t beat it.
I spined that lucky wheel and got the car. When I came out a ranked 2 play blew me up
Nice place buy ins are cheap $5 black jack $1 small blind $2 big blind texas hold'em I like that I can see a flop without it taking all my chips they got full bar and reastrunt very cool
Love to have some drinks and food at the bar. Mica, and Alendra are the best bartenders! They are always nice to us, and professional.
Okay people, if you are near... or not. This place is delicious! Was kinda nervous because you never know with casinos and didn't want to be smelling smoke while eating. No smoke smell and the food was fantastic as was the waitress. We ordered her favorites, I got the bbq chicken salad and hubby got the orange…
The blackjack dealers were inconsistent when it come to paying blackjacks; they were cheating. I spoke up and they threw me out.
Also they waste time by passing around their stupid banker sign stopping thier
Making customers wait two hours to play is disrespectful. There are 32 people waiting, yet there are no dealers available to open a table.
Well went there to eat and play some cards food was good but never got to play cause only couple tables were working locals had both tables after at least 2 hours still no open seats so we left disapointed
Don’t play baccarat up here they have the most rig card if u bet bonus the only number that are goin to come is 8 and 9 even if it’s a natural or 2 card or 9 card it’s bonus killer decks up here you better off goin to a la casino instead of here not worth yo drive they cards are set up in all games you only have a chance to play poker
I randomly come to the casino I was just cruising by the 14 to Bakersfield. I stopped by with my wife and play poker and have a good dinner. It was the discussion going on. There’s a little white guy in a Mexican guy arguing I noticed that
It’s really sad. I normally go for the tournament games to earn my hours and have fun with my family that date on January 6, 2025. There was a tournament going on with a lot of people. We all have fun good days and bad days they got me out of the tournament I lost. I walked away happy because I had fun I lost but I…

At 118 20th St W in Rosamond, about 53 miles from Downtown LA as the crow flies. It's a state licensed card room.
It doesn't stay open all night. The weekly hours are on this page, taken from its Google listing, and it's worth a quick call to confirm before a late drive.
No. Card rooms in California aren't allowed slots. You'll find poker and table games like baccarat and pai gow instead. For slots you need a tribal casino.
