We stayed at GF last month, and there were no visible signs, or cast member rumblings, about 1900 Park Fare reopening any time soon, or ever again.
In contrast, we "heard" that Bibbity Bobbity Boutique and the Garden View Tea Room were next in line for reopening, and were expected to do so in late 2024/early 2025, after the current (and already delayed) round of construction is finished. Obviously, take that with a giant grain of salt, as this was nothing more than idle gossip and speculation from front-line cast members. Plus, even if that is Disney's firm plan at present, we all know those plans can change drastically and often!
