I´ve been there twice, and had wholly different experiences. The first one was fabulous. Not only did I eat the best lasagna ever (with silken tofu), it actually remains one of my favourite meals in almost 40 years.
The second one was just the other day, at their new location, which proved to be nearly inaccesible. After taking two different underground lines and a train to San Cristoforo, we were confident it was just a short walk. However, as the train station is open on one side only (the "wrong" one), we ended up having to take a taxi from there. The driver was unsure where Mudra was (understandable, as they just opened), and we had to ask around until we finally found it. Maybe some locals can write directions so that folks can actually find it in the future. As if that weren't enough, they had a blackout in the area and no electricity, but that problem was solved within some 15 min. We finally ordered, and all five dishes plus two starters were average at best. Luckily I had already been told by the friendly waiter that it wasn't the same lasagna, but this one was slightly salty and far from the level of greatness they previously showed. Desserts were not stellar either, especially the almond pudding that was plain mediocre. It seems like the reason why they moved was space; now they have quite a (dance) floor and I imagine such activities are a top priority for them, perhaps at the expense of the food. Regrettably, I see no reason to return to Mudra.
