RE: How much is too much?
I used to eat at Arnies in Grand Rapids (West Side) years ago... But you pay 7 or 8 bucks for a sandwich and only be able to only eat 1/2 of it... Granted they started out with Texas style cut bread, but then there was a good pound of toppings in there also... I cant stuff away as much as I could when I was in my 20's, but they where the best at the time! Probably should go try them out again.... Considering they have a place on my side of town now...
As for is it worth it? I guess it depends on the quality of product they put in the sandwich... And your personal taste prefrences. If I pay 8 bucks for a sandwich, get 2 meals out of it, It's built to perfection, that only comes out to 4 bucks a meal! Well worth it in my book!
