We also love Murano, however OP mentioned that they are sailing on Infinity, which is an M-class ship. They removed the Ocean Liners restaurants from all of the M-class ships that had the same menu as Murano. Those ships only have Tuscan Grill, Le Petite Chef and Sushi on 5 so on those ships we'd choose Aqua Class to dine in Blu as long as the cost differential between verandah and Aqua wasn't ridiculous.
