The Pink Door has been recommended to me extensively by several people, so I took my boyfriend there for his birthday. The ambience is great, particularly its location on Post Aly and the bar area -- there happened to be a live three-piece band there that night. The bar area is much more intimate than the main dining room, in which we were seated right next to the waitperson station and where most of the foot traffic passed by -- although they had, on the phone, promised "the most romantic table in the place".
The lighting is flattering, the knick-knacks and decor very romantic. However, good restaurants for me mean more than just ambience; it's all about the food. And the food was... okay. Not great, not terrible, just lacking in imagination and flavor. I had a roast chicken in grape juice -- while an ample portion, the chicken was somewhat dry and desperately needed salt. My boyfriend had the lamb, which suffered from the same problem. For the prices The Pink Door charges, I would expect, at the very least, a properly cooked roast chicken.
The wine list was decent, and our server seemed to know his winemakers. A dessert course of tiramisu was paltry in size but decent (again, not great, not bad).
I'd recommend going there for a drink (the gin gimlet was tasty), but if you're going to spend upwards of $100 on a meal, take it somewhere with fantastic food.
