I live in Mykolayiv, small city in Ukraine and we have similar venue here called "Moloko" (milk in ukrainian). It's not snacks or tea/coffee that matters, it's community and events that happen there.

Owners actively encourage socialising, there are events almost every day and it hosts several clubs. In fact I just returned a few hours from Mafia club meeting there.

Also, they encourage to host your own events there, for free. I. e. they get paid from visitors and you get venue. You can also take higher price for your event if needed.
