What does "two-meal" mean in "There's nothing that could get him away from that two-meal town."?

It's a quote from the movie "The Godfather II", Tom and Frankie's scene:

Frankie: Did my brother go back?

Tom: Yeah, don't worry.

Frankie: He's ten time tougher than me-- my brother. He's old fashioned.

Tom: He didn't want to go out for dinner. He just wanted to go straight home.

Frankie: That's my brother. There's nothing that could get him away from that two-meal town. He could have been big here, could've had his own family.

English is not my native language, BTW. I think "two-meal" is an adjective to "town", but I can't understand its meaning.

Solution 1:

A 'two meal' town is short of the usually expected three meals a day.

The expression is similar to another idiom which describes a town as being short of the expected number of horses :

A very small and unremarkable town that is typically regarded as dull or boring. I can't wait to graduate high school and get out of this boring, one-horse town!

Note that both expressions accept a certain quality to the town - the place is not utterly destitute. It just doesn't have enough to be an attractive prospect for anyone to stay there longer than is strictly necessary.
