What a find! An amazing Italian restaurant worthy of a Michelin star. Only a couple of customers can fit along the counter along the kitchen where Yoshiki Tamazawa whips up course after course of amazing Italian food...and that with just one arm since he lost use of his right arm due to a stroke. This was our dinner: plate with chestnut butter broth, apple walnut creme salad and shako (a type of shrimp) on a daikon radish slice, grilled assorted veg, butter garlic oysters for my husband, soft slow-cooked beef tongue with almond for me, homemade gnocchi with his signature tomato sauce made from 3 different local tomatoes, tender juicy lamb with rosemary, duck breast with dark berry sauce, spaghetti with assorted mushrooms, spaghetti with cream and wild boar sausage (so good the we begged for an extra portion and we got it😉), and finally a heavenly panna cotta with a sauce of reduced red wine and orange. Not only was the food superb but the intimate atmosphere and the personal contact with Yoshiki and his wife Seiko made this dinner an unforgettable celebration of my 60th birthday.
Note 1: When we dined there, they didn't have a menu per se. They do 'omakase' which means you leave it entirely up to the cook. I think we paid around 15,000 yen for the entire meal of 7 courses. In the end it was eight courses because we were able to ask for a half portion of duck and a half portion of lamb for the meat course since we could not make a choice. Please do ask what the dinner that day will cost and/or tell them what your budget is. And also communicate if you have allergies or anything you do not like or cannot eat. For example, I was served the beef tongue instead of oysters. Also note that most dishes were served as a double serving on one plate to be shared.
Note 2: Due to some horrible setting in google maps (possibly favoring the business accounts that pay advertising fees to google) you really have to zoom in to see the location of Di Grotto. And even then, the name of the restaurant may not even be displayed. So I've added screenshots of the map so you can visit Yoshiki and Seiko.
