It all comes down to money and profit. Maybe they just don't see it as profitable or maybe the deal, if any, that they got wasn't worth it. Also, having connections to apps like those require paperwork and such. Maybe La Bou doesn't want to go through it?
Not sure.. Some restaurants have exclusive deals.. Maybe try them on grubhub or another food delivery app. Like McDonald's only uses doordash.. Maybe labou only uses a certain one as well. Hope that helps!
