What a gem! I was working remotely from my hotel room at Rio and needed a quick bite to eat. Luckily, Rio recently remodeled and opened up a food hall with a variety of eats!I opted for an american classic, cheesburger and fries! I also want to mention that their pricing here is unbeatable! $8 for a burger itself, but $16 for a full combo of the burger, 50/50 fries/onion rings and a drink! This deal was too good to pass up.Now onto the food. The cheesburger was a perfect smash burger and I loved the crispy edges. One thing I do wish they had was lettuce and tomato. I love the fresh balance it gives to the rich burger. The fries and onion rings were perfectly fried and the team here is very generous with the amount of ranch and bbq sauce they give. Side note that I don't think has anything to do with the restaurant, the soda machines all around the food hall seem to not be working properly. The one closest to attaboy was not sweet enough and the others had a weird syrup flavor. Overall, i'll definitely be back for more especially with the competitive pricing they have to offer. I have my eyes on the $4 ice cream sandwich for a sweet treat!

Attaboy Burger? More like absolute bummer.I've been working through the Canteen Food Hall at the Rio Hotel & Casino, and it was Attaboy's turn at bat today. There was a big pool (billiards) event at the Rio today, so even if I wanted to stand in line for once, using the kiosks for the food hall was a better option. They accept Rio dining credit and points for payment, which is as easy as a swipe, a PIN entry, and a few more taps of the screen.It felt like either a good or bad sign that their menu is so simple. I went for the Double smash burger ($12.00) with a side of The 50/50 ($7.00), aka both onions rings and curly fries. Despite being a double patty, the burger was small. Even worse, it was bland, despite the included "fancy sauce" and my attempts to add any number of additional sauces on the side. The cherry on top was that the beef patties had few if any crispy edges, which is what you look for in a smash burger.The beer battered onion rings were pretty bland too, and the curly fries were plain, on the dry side, and overwhelmingly served as matchsticks rather than the lengthy spirals which you hope to get.I was considering giving them some benefit of the doubt at the ~2.5 star fence, but then they didn't provide me with a cup for water when I asked. Even if they were out of water cups, they still had plenty of alternative cups to offer. I have been able to get a water cup for free from at least one of the other food hall businesses, but it would have felt really awkward to do so while holding a burger.With only two more places remaining for me to try, Attaboy Burger is the prohibitive favorite for worst food option at Canteen Food Hall. Considering both quality and price, I would have preferred getting most if not all fast food burgers over this spot. I will almost certainly not return here for any reason.

We visited the newly renovated Rio Hotel & Casino Canteen Food Hall and tried Attaboy Burger. The young man provided great customer service. Our order arrived within 10 minutes. Attaboy Burgers were grilled fresh and we requested for one medium well and one well done. We ordered a single burger and a double burger (double patty) both with American cheese, caramelized onions, fancy sauce and pickles along with seasoned curly fries. Attaboy Burgers were good, tender and the patty was thick. It seems like they use lean meat for their patties due to the texture and thickness of the beef. Seasoned curly fries were ok. I could not figure out the seasoning used but could taste the salt. It would have been better with less salt. Fries were crispy. We definitely will stop by Attaboy Burger and try other items on their menu when in Las Vegas.

Great burger for an excellent price! Seriously though, $8 for a smash burger in Las Vegas?! Count me in! Attaboy Burger is located in the new Canteen Food Hall at the Rio Hotel in Las Vegas, and I was visiting as part of a video to try a little something from most of the spots located here.Attaboy Burger and several of the other places left me legitimately impressed and surprised at just how much I enjoyed it! The food hall space is a bit small, but honestly kind of cozy and comfortable. Attaboy is very noticeable with its colorfully yellow decor, and it was one of the first spots I was drawn to. I also found myself impressed by the prices here, with the single smash burger starting at only $8 - that's a steal in Las Vegas!! The burger was ready very quickly after ordering and service was very friendly. Upon trying, I found it well-cooked, tender, cheesy, and very flavorful. It's a little small, but I feel like it's enough to fill you up for a quick bite or for lunch. I enjoyed that it wasn't overpowering or heavy and felt the sauce, meat, and cheese inside all perfectly complimented each other. All that being said, if you're craving a cheap and flavorful smash burger, definitely stop by Attaboy Burger! This is a great new addition and wonderfully tasty spot in the Rio Las Vegas!

To be honest I have never heard of this burger joint before so when Ibm was in the Rio casino food hall area I decided it try it. I was actually not expecting much bc it's a small fast food type looking place in the food court. The burger took a minute and it was actually worth it. It was one of the better burgers I have had in Vegas in awhile actually. Crispy bacon not fatty rubber bacon like most burger spots give you. I also got curly fries which were good and it came w/a good ranch type sauce as well. I would definitely go back here for a burger again. Impressed for a little food court spot.

Texas Toast Smash Burger: 5/5 delicious. Flavorful but still juicy with bits of crispy bits. Smash Burger done to perfection.Curly fries: 3/5 taste like those frozen ones from a bulk store. Gets soggy and sad fast. Not only soggy it becomes a bit rubbery. Overall: great burgers but a disappointment for the fries.

Their burgers, fries, and ranch was sooooooo good. I like a good ranch, but let me tell you, this ranch was out of this world. The fries were crispy and the sauce they put in their burgers made them tasty as well. Absolutely no complaints. I would come back and think it's worth every penny.

Not a fan. It's super greasy, no flavor and it's expensive. I wouldn't go back. Service is good though. The dining area needed its tables wiped down.
