I get my sandwiches at the same place as Ryu, Roma\'s. My all time favorite has to be:
Dutch Crunch, with either turkey or roast beef (usually turkey), mustard, lettuce, garlic sauce, and ocassionally onions. I usually take a regular size (6 inch long).
My one regret when I went to NY is that I didn\'t try that famous sandwich place. The name of the place escapes me at the moment.
