• private room dinner, party of 20

  Hosted a group of 20 in the Executive Room. Danielle from their team was easy to coordinate and work with during the planning phase and Tim our head waiter was excellent on the night of and made it a great guest experience. Gregory the General Manager also welcomed us for the evening as well. Ambiance, food, and service from start to finish were all A+. Would highly recommend whether a party of 2 or larger group.

• private birthday party

  Booked a private birthday party at Mastro’s. They were fantastic. Food & Service top-notch. Planning was accomplished 100% via email. Easy.

• semi-private holiday dinner, party of 8

  I must say that life music, support staff and the bathroom attendant were extremely pleasant, attentive and hard working. This review if for the GM, his events’ leader (Danielle) and waitstaff (Julian). We booked a semi-private party of eight with a set minimum of $250/pp. The whole booking experience was unpleasant, dry and un- welcoming. Let’s be honest, the quality of the food and entertainment is there. Tis the season; and, if the space is not booked by one party, it will be - by another. Regardless, none of it should be reflected on the level of communication, courtesy and hospitality that are a part of the overall experience with a venue from start to finish. I initially left a voicemail for the events’ point of contact and followed up in an email. She never bothered to get on the phone and to even introduce herself. So the whole booking experience was done via email. Excuse me, but a 5% fee associated with the process for what? To copy and paste questions and wait for my answers? Your hostess could do that. At some point, I had made an attempt to contact the GM to address the situation early on. I called in the evening to make sure to catch him. After having heard me out on the phone, he directed me to email him with the details as he “could not hear what I was saying.” I didn’t end up emailing him because he did not seem like he cared for the whole situation to begin with. Had he had enough care for the job he does and the experience the patrons have, he’d ask me for a phone number to call back at the next day before serving hours to address the situation. Lazy if you ask me and completely unaware of what hospitality entails and what business he is supposed to be the face of. You can do better Mastro’s, given the fact that the place is a self-running ship essentially at this point and all you need is to add someone who truly cares for what hospitality is about. When we arrived for our reservation, a manager, I’m guessing the GM himself, was at the hostess stand and without a warm holiday greeting, just directed the host staff to take us to our table. The server seemed to be completely nonchalant, exhibiting zero (if not below zero) sense of urgency. The drinks were taking forever, especially in the beginning (when most desired), as if he had to bring them from Ocean Prime across the street. Further, since this was a holiday gathering, the last thing we looked for was a rushed service. But it seems that we were rushed every step of the way: first, to place the food order and then to have it cleared away right at the very minute a couple of people stopped eating. Not ok. At NO POINT IN TIME, did the GM nor a floor manager come to the table and checked on us. When it was dessert time, the server advised me that we were $400 away from the minimum so we asked for the food menus to place an order to go. One of the guests first wanted to order a NY strip but ended up ordering a Porter House. When the take out orders were brought out, the runner announced a NY strip. When we asked the server why it was the strip instead of a porterhouse, his reply was, “I went with the first choice you made.” Like, what does that even mean??? Again, given the nature of our reservation, the last thing we wanted to do is make a scene so we let it go. In the end, it was a frustrating and poor experience that left a bad taste in the mouth even the next morning. I do hope that this review reaches the CEO to address the lack of service at their restaurant. To call oneself an “upscale” establishment takes continuous effort, care and attention. None of it had been a part of our dining experience. If this is how the holiday season is experienced at Mastro’s, it’s sad to think what the slow months of January and February are like.
