We had items off the menu. Appetizers: bitter salad and carrot soup. Main courses perch and trout. All dishes were superb, delicate and unique. The low carb-low fat positioning is a nice feature, but the local sourcing of ingredients really pays off. It is a nice modern looking restaurant with excellent service, and pleasant and comfortable seating. A little off the beaten path behind the Stephansplatz, and apparently more for locals rather than tourists. Highly recommended.

We ate at Loca on a trip through central Europe and it was the best meal of the trip -- the best meal we've had in a long time, in fact!

We dropped in during the afternoon to ask about making a dinner reservation. There were a few men working in the restaurant and obviously very busy, but they made time to talk to us, tell us a bit about the food and restaurant and make the reservation.

Our waiter for the night was the same gentleman who took our reservation (not sure if he was the owner/ manager...) and he was delightfully quirky and really made the dining experience. He was the only waiter working, but seemed to do a great job of looking after all the tables and creating a great atmosphere.

Food and wine was amazing, and each course got better and better! We chose the 6 course tasting menu (unlike another review, we felt under no pressure to chose one menu over another) paired with wines. Each wine was local and EXCELLENT. I think we spent around EUR 175 including dinner, wine and tip -- a little expensive for dinner, but I think good value for money!

Loca stands for locally sourced foods that are low carb and low calorie - no sugar added. But this does not mean bland. Far from it. We stay inside on a warm evening with many people outside. We opted for the 6 course menu - 46 euros - great value. Breads were nice to start, especially with a chive cream. Courses included warm white asparagus in a slightly sweet dressing, a slice of veal with squid, leak soup and you could taste but not see potatoes, pike with asparagus and paprika, beef shoulder with mushrooms, and summer berries with ice cream. This description is Rubbish but the food is not. Good service. A great wine-list and we placed ourselves in the hands of the sommelier who ordered us a delicious Riesling, helped choose some glasses of Pinot and then gave us some pudding wine. All in with a tip about 180 euros. It is very good rustic cooking and if we had the opportunity, I would love to go back. 9/10 from us. Go. You won't regret it.

I hosted a customer dinner for 15 at Loca last week and chose the 6 course degustation menu. All 6 courses were absolutely delicious as was the wine chosen by our waiter to complement the dinner. Our waiter for the evening was very attentive and gave us a description of each course as it was served. I would highly recommend this restaurant to anyone traveling to Vienna. Easy walking distance from most major hotels, great food and outstanding service!!

Very good. Lovely food high quality. Staff friendly and explained dishes well. Small place so limited dining space but really well worth the effort - I would book in advance. I would definitely go back. Excellent evening.
