Postinos is a gem. The $20 bruschetta and bottle of wine deal is impossible to beat, but even without it, the experience is well worth it. I have gone to postinos with friends, with my s/o's dad, and with colleagues to discuss work. Every time, the atmosphere was appropriate, the wait staff attentive , and the food delicious. Its definitely a great place to go if you're trying to impress somebody.
The only thing I have to complain about is that parking can be hard to find, but it is absolutely worth it.
