I visited Senti a little while back for my first ever restaurant week experience (I know, crazy) and I have to say it was a great first experience. Looking at the photos on yelp it seemed like a upscale restaurant so we dressed nice for the occasion. I was a little nervous that we may be overdressed because that seems to happen a lot in the Pittsburgh area but thankfully we were dressed appropriately.
It's a cute little place that doesn't have a whole lot of tables. It had a very intimate, date night feel to it. I would say its a place better suited for parties of 2. Smaller parties would probably be ok but definitely not large parties.
For our courses we got a caprese salad and spaghetti with meatballs and marinara. It sounds boring but it's all authentic italian so it wasn't just your average pasta. I'm not even a huge meatball fan but I really liked these meatballs. I liked that they were smaller meatballs rather than huge meatballs. Something about the smaller ones just tastes better for some reason.
As far as the service goes, I was very pleased. They waitress was very attentive and checked on us periodically. She was able to suggest a wine for our meal that we both enjoyed. The owner was also walking around checking on tables to ask how everything was which is always a nice gesture. After this experience I would definitely like to go back some time and check out the full menu. Possibly my next date night!
