Easily the best restaurant at Lake Garda. Serving creative, uncompromisingly delicious, superfresh fish dishes for decades already. Wines excellent, service very friendly, welcoming, professional with an incredible talent to make the place not feel stuck up at all. Ambience matches the food and service. Well designed from top to bottom. In every nook and cranny you see something exciting, innovative, or traditionally beautiful all combined masterfully into one stunning masterpiece.
If you want the full "la Grotta" experience start out with a Misto Crudo each, the mixed raw fish starters, then continue with many many cooked starters only one to share amongst two or three of you so you journey your way through the menu bite by bite. If its two of you you can easily go through four to eight cooked starters that way depending on whether youre willing to skip a main course. Main courses and pasta dishes are also absolutely excellent but one has to say that the true attractions (and they ARE attractions) are the starters. On a particularly adventurous night, tell the waiter to take care of the food without ordering yourself and the waiter will design your menu for you which will look similar to what i described on the top. That saves the somewhat time-consuming task of going through the many many daily changing dishes which instead of being written on a black board or the menu are recited by the waiter.
Not cheap but worth every penny. Dont go in for a quick lunch or dinner. See it as an event of your vacation and take your time and dont worry about the cost. A nice experience there will be 100 to 150 Euros per person but it will be the main thing you tell your family, friends and colleagues about.
TLDR: Cant recommend enough. Not only worth a detour, worth changing your vacation destination for.
