Wonderful tapas bar right in the heart of town. The vino kept on flowing and the atmosphere was…read morefabulous. The pimientos were perfectly salted and wine selection was excellent. But let's face it, you'll get fabulous wine all over Spain, right? That said, this spot was perfect for a snack and great company.

We came here late night, on our last evening in Bilbao…read more Most kitchens close quite early in this area, and Ad Hoc was open at least an hour later than anyplace around. The place is clean and modern looking with a beautiful chalkboard and a friendly waiter who was happy to accommodate our late-night drunken and broken Spanish. We had delicious and piping hot croquettes with a creamy interior spiked with salty ham. Their anchovies were standard but really delicious. Finally, at the bartender's recommendation, we had some Morcilla (blood sausage) with a lovely creamy puree. There is so much amazing food in Bilbao, it's sometimes hard to choose where to go to get your fix. In this case, Ad Hoc's unusually extended hours made the decision for us and i'm really happy they did!!

I must admit, it felt a bit strange going to a traditional American restaurant while visiting…read moreSpain. After thinking about it we realised we shouldn't be bias. After all we have American restaurants in Australia too and we have no quarrels visiting them. This place is a super chill multi-leveled burger house, with the main dining area where you first walk in, the kitchen half a floor up, and another dining area half a floor down (underneath the kitchen). We had one waitress looking after the whole restaurant and she busted her butt making sure everyone was looked after and happy. The restaurant wasn't mega busy but it was still a lot for one person. Needless-to-say she got a great tip. I ordered an XXL Burger and the wife got nachos. My burger was very enjoyable and the fries weren't half bad either. The pattie was cooked perfectly, everything was fresh and proportion of flavours were spot on. My wife thought the nachos were okay but they weren't her favorite. It was lathered with a cheese sauce. This must be an American thing that hasn't caught on in Australia. We do prefer massive lakes of hot melted cheese on our nachos. But hey, everyone has a preference. Service was amazing. The place was clean and looked the part of a modern burger restaurant. They have beer. What's not to love about this place! The only thing that was a slight drawback was the metal chair I sat on would pop in and out every time I adjusted my position.

Surprisingly good This is an American style diner in one of…read morethe tapas capitals of Spain. We visited because we needed a break from tapas and had a surpisingly good experience.

It is omakase style and you choose if you want small 4 plate style, medium 6 plate, or large 8. The menu changes every day so it's a surprise but it is INCREDIBLE! Each dish had so much flavor bursting and flavors contrasting in a great way. Our waitress was fantastic too and took note of any allergies or things we didn't like in order to alter the food so it was perfect for us. Overall AMAZING place to eat in Bilbao and a must try.
