I think you need to think about what you want and get out of Starbucks. Do you drive there? It sounds like after dinner (or before?) You load up your toddler in a vehicle and drive to Starbucks, and each get a drink and sit and chat. Is that right? The factors are: Starbucks is clean, feels "adult", you have no responsibilities there, and the only thing to pay attention to is your family, and it is not the place you've been for the last 22 hours. The feelings you are seeking are: family time, low distraction.
My proposal would be a walk in your own neighborhood when the weather is OK (Even if it is cold, or slightly wet, but I'm not saying you have to do it in the pouring rain or below freezing.) It can be a slow walk, and just a mile or two. Strap the kid in the stroller. It is free. You can talk to each other and look at things. It is out of the house. You don't have to walk TO anywhere. You can bring mugs, or not, and just walk to "that red house that is about 15-20 minutes walk away." If you have a park that's great too, but if not, it could just be "That one house with the weird mailbox."
If you live close enough to "things" to walk it could be errands: The post office, the pharmacy, the bank, the grocery store for 1 or 2 things.
Assuming it is nice enough to walk (Between 32 and 85 degrees, no to light rain/ snow) about 9 months of the year, I'd give you Starbucks permission for the other 3.
Some areas have free "art walks" Gallery openings on one or two evenings a month. You could try to find that, but I'm not sure how that works with a kid.
If you can't walk in your neighborhood, and can't go outside 9 months of the year, I propose you MOVE!
