Mine would have to be a meal at the French restaurant not far from where I live. It's authentic bistro-style, with menus written on blackboards, and incredible food.
The service is friendly and down to earth. Even though a lot of the clientele are rich, they treat everybody the same, which is nice for us poor people.
I'm not a big meat eater but I had the seven-hour roasted lamb with herbs and leeks, scalloped potatoes and green beans. It was all melt-in-your-mouth delicious. My vegetarian hubby had an incredible terrine.
