My husband and I visited Il Tetto on a Saturday afternoon. Luckily it was a gorgeous day so the rooftop was open. We were there early so while there was a crowd, it was nowhere near unbearable. We both LOVED our cocktails - one had tequila & beets, one had bourbon, balsamic and basil. Both amazing (and around $11 each), we stayed for another round.
We sat at the bar and had good service, but didn't order food. The view from the balcony isn't anything to write home about but it was still a nice area to linger in for a bit. We also weren't huge fans of the roped off elevator line situation, but our wait wasn't long at all. Overall this was a great place to soak up some sun on a lovely day.
