My recommendation would be Marcel's Bistro and St Tropez located at 315 King St W in Toronto. The service is impeccable, food is absolutely delicious and the atmosphere is very relaxed and intimate.
I sat on the back terrace at St Tropez which is very nicely decorated and has ivy leaves which travel up the walls and makes for a very nice experience. Also, They have live pianist who play jazz and helps set a nice ambiance.In My Opinion, this is the best French fine dining restaurant in Toronto and the prices are reasonable for upscale quality food.
