Senti ownership deserves only 1 star, but the extra star is for the chef because the food is truly delicious. I have been twice, once with my wife and another couple and a second time with a group of 5 other friends.
The first time, it took over 45 minutes for us to be seated against a reservation for which we were on time. The manager did buy as an appetizer and round of drinks but when we sat down the service remained extremely slow. However, the quality of food and manager's response to our long wait time drove me to giving Senti a second chance.
When dining with a group of 5 friends, we were sat on time (it was a Tuesday). The process from the time we sat down until departing the restaurant was 2.5 grueling long hours. We enjoyed ourselves and filled the long periods of time where we were waiting to order, waiting for our food or waiting for a drink with fun and entertaining conversation. However, by the time we found ourselves waiting again for the bill, we all looked at each other thinking "let's get the heck out of this place and never come back."
I am a pay for performance tipper with a range from 10% if you are a complete disaster to 35% for an amazing experience with a standard average of 20%. I was even more annoyed when an 18% gratuity was added because there were 6 of us and I did not get my opportunity to express my discontent via what would have likely been a 10-12% tip, so thanks to Yelp for helping me to express myself.
