I have experienced all three of the mentioned places many times over the years. They are about equal in my book, with little 'tweaks' in each business to make them acceptable.
I lived for years in SoCal where
In n Out is the undisputed champ of the FF Burger empire(in that region). Nothing out there comes close...
in it's catagory. Once you step beyond the drive-thru or minimum menu type of stand there are a few that come close (ie:
Farmer Boys) and perhaps some others.
Here in the Midwest,
Steak and Shake is a long established business. It has a much broader menu, and centers on ordering with a server then sit-down eating with a drive-thru business "on the side" (no pun intended). The Burgers and other sandwiches are quite good. I don't care for the shoestring type of FF, but that is an individual preference. My favorite sandwich there is the San Francisco Melt.
Last, but in my book,
NOT LEAST, comes the new guy (in our area)..
Culver's. As stated before I really like their sandwiches and custard. They seem to have struck a balance between order at the counter then sit-down to eat and a drive-thru service that works for me.
I guess I would not be willing to assign a
first,
second, and
third place value on these three business's. I think the food quality is close to equal at all three. For me it is a matter of access.
In n Out is out West. When we make a run 'home' to see friends and family we look forward to hitting an
In n Out as soon as we get close to Vegas or SoCal. Here in Indiana the distances are shorter, but still contribute to the choices we make.
Culvers is 11 miles west in a small town and next to a Super-WalMart and the I-64 interchange...read Convenient.
Steak and Shake has a couple of locations about 15-20 miles East, in the Metro-Louisville area. Now Louisville is Not L A as far as traffic goes, but it also isn't small town Indiana for ease of access and traffic either. So we tend to make more stops at
Culvers because we shop in the town near it, without feeling like we are 'lowering our standards".
All three places serve very good sandwiches, I have no trouble recommending any or all of them .
