I've been fortunate enough to have some excellent dining experiences. My first was in NJ in a place called Good Fellas (I think it was really called this!) It was an authentic Italian restaurant. We had a meal that was about 7 courses and it was so amazing. We started with buffalo mozzarella, fresh tomatoes, with olive oil and garlic. Then we had our soup, then pasta, then entre, then dessert, then espresso. I think there was more too! The food just kept coming and we dined leisurely for about 3 hours. The service was impeccable, we were not rushed in the least.
I once went to L'Espalier here in Boston, the food and service were phenomenal. The staff was nearly psychic in taking care of your every need. That was way beyond my budget but I had a gift certificate that was a bonus from work. It was for $100 but the meal was $250!

I had no idea it would be so much but it was excellent.
Another great meal I had was on the south shore of MA at Tosca. It is a 5* restaurant as well and you just would never expect it there. Perhaps in NYC or LA, and now even Boston, but not Hingham! The presentation of the food there is gorgeous. The dessert was really excellent and GIGANTIC!
I'm a foodie so I could go on and on and on and on...
