This reminds me of that Woody Allen movie where they open a cookie shop next to a bank to set up cover while they tried to tunnel into the vault. Meanwhile the cookie shop takes off as a successful business and they are stuck in a quandary as to whether they should rob the bank or not...
What title it is?
I want to watch it.

I don't know about any Woody Allen movie like that but it sounds a lot like
Larceny, Inc. (1942)
with Edward G. Robinson and lot of other talent.
"Three ex-cons buy a luggage shop to tunnel into the bank vault next door. But despite all they can do, the shop prospers..."I do recommend it.
Maybe Woody Allen did a remake of this.
