I am looking for places to take someone out for their birthday next Friday or Saturday night in Philadelphia. The neighborhood doesn't really matter that much but I was thinking more along the lines of Rittenhouse, Old City, or Center City. I guess I am somewhat open to the type of food although I know that I don't want anything asian. Maybe something like American, Spanish, or Italian. I'd like to try to stay in the price range of something less than $150 for everything including tip and drinks. I have read several reviews about the quality of food at various restaurants but I guess the reason that I am asking is that I think that for an occasion dinner I would be more inclined to put an emphasis on the atmosphere than having the absolute best food possible. In other words, I am looking for something that's more romantic/quiet but still worth going to as far as the eating is concerned as opposed to a noisier place even if the food is better.
I also need to find a place for good dessert as I may possibly take her out to dinner on Friday night and then some place else for dessert in the city on Saturday. Suggestions are welcome and very much appreciated.
