Overall, Mangiamo is a quality restaurant that works for entertaining friends or family, which was why we went. This review is only based off of one experience, so bear that in mind. We also brought a 3 year old, which they accommodated without fuss (more details on that below).
Location: In the he
art of MB
Mangiamo has a nice location in the hear of downtown MB, though no view of the water once you're inside (typical of most downtown spots, unfortunately). It's easy enough to access if you park in any of the paid public parking options around the area.
Food: Good quality but not amazing taste.
I'd say the overall food quality was pretty strong. The taste of our dishes though was good but not amazing. I had the duck, because it was a special and sounded great and like it would be a refreshing twist. It was good - not great. Also tried the risotto, which we ordered for my daughter, with the same result - solidly fine.
Service: Great!
We booked our reservation easily through Open Table, and they were gracious about having a three year old in our party. In fact, our server went WAY above and beyond to keep her happy and entertained. He even went to the back office and got paper and pens for her to draw with (we forgot our usual coloring arsenal in the car) -- and then proceeded to open each pen to demonstrate the color for us. Made quite the impression with our daughter, needless to say. He then rewarded her drawing prowess with a free sundae ; )
Usually fine dining restaurants are standoffish about kids, so this was rather exceptional, imo. Beyond that, he was very attentive and helpful across the board.
Atmosphere: Nice enough. 
We sat in a cozy little wine cellar area toward the back, which was kind of neat - though a bit random because it's so separated from the rest of the dining area. I could see some people loving the seclusion, but others may feel isolated. Depends on why you're there I suppose.
Overall, the vibe in the place is pleasant but there's something that's just not totally warm or inviting about it. It also feels rather cramped.
Nothing particularly remarkable or interesting about the decor or style either.
Should you Go? Sure, but don't rush.
Mangiamo's is worth a try and you'll probably have a pleasant experience, but it's forgettable at the end of the day. We were there to host my dad, in from out of town, and it doesn't really fit the bill for a "special occasion" type of spot where the food is remarkable and the atmosphere compliments the excitement of the evening. For a causal dinner out if you're local though, it's fine.
