I'm willing to give it another shot but I went here last night and the sandwich, while hefty and meaty lacked taste. I had it plain and sweet so maybe more sauce or hot peppers or other toppings would have helped.
San Francesco (couple min walk away, where I go much more frequently) is $1.75 cheaper and a more reasonable (eg. smaller) portion for one. Also a longer wait at California.
Their website states a veal sandwich 500 calories, 25 Grams of Fat & 20 Grams of Carbohydrates. "I think I'll type that up on my invisible typewriter" Chief Wiggum.
ETA - OK, OK... I guess I can't update my review after only a few days but went here as part of a Yelp event and had part of someone's chicken, cheese, mushroom sandwich. Much better. Next time I will order a sandwich with cheese and extra sauce (medium heat) and would go to a 4 if all goes well.
