Locale was small and intimate. Had a business dinner there and unexpectedly our table was a small, tall bar table. Being small made it awkward and difficult to manage with drinks, appetizers, steaks, sides and later dessert. Cut of steaks available are top of line and preparation was good. The service in person was fantastic. Overall food was good, but ambiance, table size, and table location by bar made it a bit uncomfortable with several groups trying to cozy up to the bar to get drinks before dinner. Last but not least, I was charged $90 for the reservation and the $90 was not deducted from my bill. Having receipt in hand, I called and my contact info taken and was told a manager would get back to me. After 12 days, with no manager call or resolution, I disputed the $90 reservation charge with my cc company and I had it taken care of. I had high expectations but after a $300 dinner in a crammed setting, and no resolution to the reservation charge I will not be going back, as there are too many other options in this city.

Great place. One of best in Chicago. It's a great vibe and pretty interior. Feels so cool to dine here. Service was great and friendly and explained anything you wondered about. Now the food. We had the lobster and corn foie gras, the churros, and the prawns first. I would say prawns and foie gras were great and highly recommend. The churros were okay, nothing special and pricey for being nothing special, would skip those. Then we had the arroz cremoso (which is a seafood risotto), the besugo (fish), and bone marrow potato puree. All amazing. Fish was perfectly cooked and the risotto was a must have. Enjoyed the potatoes as a side with the entree. Loved it. The fish is amazing here, don't think you have to get a steak , the seafood is some of the best in Chicago. For dessert we got the golden chocolate hazelnut cake, I really enjoyed it. If you like chocolate and hazelnut, you can't go wrong here. Thought it was pretty presentation and tasty. Good way to end the meal. Overall, must try this place. Perfect for a date or if you want to show people a cool Chicago spot. Can't wait to come again. Next time I'll try a steak.

I don't review restaurants very often anymore, but Asador Bastian is one of the best new restaurants I have been to in the last couple of years. In a city where steakhouses rule (i.e. Gibson's, Bavette's, etc.), it is hard to create a new steakhouse concept that delivers both on food, service, and ambiance. Chef Doug and his team have done just that. I have been here now on multiple occasions just to confirm it was not a one-hit wonder and it has delivered each time I have been here. The cocktails and wine list here are also fantastic - you can't go wrong and the somms will steer you in the right direction. If I had to recommend a few things that you MUST order, it would be as follows: - Tortilla Espanola (with jamon or caviar) - Bluefin Tuna Carpaccio - Steak (I've had the dry aged Holstein and a couple of their specials -- all great) - Garlic Prawns - Octopus - Truffle and Iberico Rice - Bone Marrow Potato Puree I have not yet had the whole fishes yet but I can't imagine it not being amazing -- but the steak is really good and you should get enough of it to split among the table (it is priced per pound). The price point will be in line with other fancy steakhouses, so it's probably not a place you can dine at every night, but certainly worth it for a nice night out or a celebration.

Celebrating a birthday on this occasion, our server Yousoff, went above and beyond for us! He explained the menu thoroughly and helped us with ordering and getting a little bit of everything to taste a wide variety. If you dine at this amazing place please ask for him as your server, you wont regret it. Ordered 2 steaks and they were amazing! The mashed potatoes with bone marrow were delicious and the beef tartare was AMAZING! Honestly everything was scrumptious. The dessert was dynamite as well. We loved everything about this place. Starting from the service, to the relaxed ambience, and the unforgettable food.

10/10 all around Vibes/ ambiance is immaculate. Food is delicious from seafood, to steaks to apps to side, etc The service was the best part and that is saying something at a restaurant if this caliber. Our server, Juan, was amazing and helped make it the experience it was.

Very cool intimate Spanish steakhouse in a reconfigured townhome. The service was great, the vibe was awesome and the food was fantastic. My wife and I split the 1.75 lb Galician steak and it was incredible. We tried the mashed potatoes, caviar churro, bluefin tuna, beef jamon, and asparagus salad. The blue fin tuna was my favorite appetizer. Very unique flavors. I could have eaten 10 plates of it. Beef jamon was awesome. My wife really like the caviar churro. I thought it was okay. Two small bites for $32....probably not worth it. Asparagus salad was fine, but not something you need to try. The drinks were awesome. Daisy Mezcal, Dirty Dirty and Old Fashioned were all great. Overall a very unique spot that is great for special occasions. It's a higher end place, so we expected a big bill. It honestly ended up being pretty reasonable all things considered. Probably best to split a steak instead of getting two separate ones which will save you $100.

Excellent. Fabulous. Decadent. Whew, still breathing heavy after this wonderful meal. Truly a 10/10 dining experience. We were seated in the barroom, which is incredibly cozy & sophisticated. Liz, our waitress, was very helpful in guiding us through the menu & ensuring our meal was well-balanced. The caviar churros, tortilla espanola, picon punch, & bone marrow potatoes were the easy highlights... each bite delectable. They also offer a variety of steaks & seafood. Tonight, we had the tasty dry aged steak Holstein. We will definitely return & highly recommend. This is an excellent spot for a special occasion.
