Each year, my husband's birthday rolls around and he loves steakhouses. We are always trying new ones, since that's part of the fun for him. This year, he chose Mastro's.
We had our reservations for 7pm and arrived a little early. We were seated right away... I think the time of evening that we were eating was on the early side for a Friday night. There was a lounge singer near the front, singing some variations of songs by Post Malone, The Weeknd, and Miley Cyrus. The music was fairly loud for people sitting in that area or at the bar, and thankfully we were seated further away.
The ambiance was not as cozy or intimate as some other places we've tried, and doesn't have much personality. Our waitress, Heather, was excellent and attentive without being overbearing. She did recommend that we select less sides stating that portion sizes were large, and she was right. Even with taking off one of our side dishes we had plenty of leftovers.
The food was fine... nothing that made me want to go back again, but certainly tasted fine. I think the lobster Mac and cheese was my favorite. The wedge salad was actually chopped iceberg, the twice baked potato and creamed spinach were passable. My husband's steak was fine- he said the food was fine for him too.
They did bring out a cheesecake with happy birthday and my husband's name written on the plate, which was a nice touch and we appreciated it. The cheesecake was incredible! Fluffy and delicious. Best part of the meal and a nice way to end the evening.
I'm not that familiar with places in the seaport, but if I were to recommend a steakhouse in Boston I'd say you should try Mooo.
