Insta makes it possible. As soon as a chic restaurant opens in Vienna, it is already full to bursting - as is the case with "Rascal" as part of the "Wilde Aparthotel" in the old k. u. k. Central Post Office. As with many hotel openings, the focus is on the brasserie type and thus the tried and tested, implemented by Tamas Kiss, previously at the stove in "Seven North". The tables in the high, noisy vault are nicely spaced out. And the concept ensures intensive contact between service and guests. A trolley pulls up to serve Caesar salad or beef tartare - as with furniture or watches, the retro trend is also making its mark in the culinary world. If you can't make up your mind from the six bites on offer, go straight for the "snack tower", where the original sauerkraut arancini with parmesan is the only thing that stands out. A strong recommendation: tuna carpaccio with chili and ponzu - sashimi-grade fish, marinated with verve and the most exciting item on the clearly laid out menu. A nice gag: the "spinach & ricotta raviolo" - one of only six main courses - is actually a giant thing made of silky dough and flavored with lemon. The ribeye with red wine sauce and green pepper (also retro) or the halibut tranche in a vegetable broth are also rated "solid". And when the waiter approaches with a bowl of chocolate mousse, say "Say When" in the sense of stopping for the serving spoon. Then olive oil and salt come into play with the chocolate - whether you like it or not, you have to communicate here too. Incidentally, "Rascal" translates as "rascal" or "cheeky bastard" - an association that comes to mind when you look at some of the wine prices.
