I was pretty unimpressed with Lago- not to say it was bad but I had higher expectations. Everything was just mediocre with the exception of our drinks. Tapas we had were: Ahi tuna (very bland, not fresh tasting), Octopus (chewy, pretty subpar), Beef carpaccio, Lobster gnocchi, and Wine Risotto (those were all fine but nothing to write home about- especially when factoring in the price). The service was just okay. I feel like servers at an "upscale" place like this should have a bit more initiative.
The ambiance is nice and the fountains are neat to watch, but I'd definitely choose some of the other fountain-view restaurants over this. The music inside was also a bit loud for my liking. Not compelled to return..... maybe for a cocktail from the bar but that's it.
