Went to Otto near the gondolas and then later here. Both places we ordered the exact same pizza, margarita with extra basil. The pizza at Otto was much much better. \n\nGrimalidi is a decent pie but just doesn't have the authentic Italian magic which Otto has. The crust was doughy and dry, the cheese tasteless and clumpy, the sauce was fine. Lastly, the ambiance at Otto is much better than Grimaldi.\n\nPrices are the same at both places, so no reason not to check out Otto
