El Gaucho Bratislava
It is very nice bar and restaurant. There are 4 rooms with a lot of possible configurations of tables. It is good for big groups as well as for a couple. Reservation is highly recommended, especially for big groups.
As you walk in there is a long bar with a very impressive choice of drinks. There are few professional bartenders. Food is very good, the service great and you will not spend there a fortune here unless you try the Kilo Steaks they serve with all the trimmings.
