Any cafes that would be less crowded today?

Does anyone know of any lesser known/ comparatively quieter cafe around Sector 43? Me and my partner plan on just meeting for 1-2 hours, and don’t want to spend those 2 hours waiting for a table to be empty. Most places I’ve called aren’t open to a reservation today. Any help on recs (or any cafes that take reservations) will be appreciated. Thanks!
