I can't give any info on the IHOPs because we've never eaten at one while in Orlando but we're Golden Corral experts! First let me tell you which GC NEVER to eat in--the one on International Drive @ Sand Lake Road. Service issues galore, dirty plates and glasses and lack of attention to what needs refilling on the buffet. Never again!
Now, the other three in the Orlando area that we have eaten in have been good. The one on 535 in Lake Buena Vista is relatively new with a very good buffet selection. One on 192 (East) is also good but is almost always crowded. Our very favorite Golden Corral anywhere is worth a drive for us. We LOVE the GC on Colonial which is quite a distance from WDW but not too bad from Universal where we usually stay and play. This Golden Corral has excellent service, is very clean and has, without a doubt, the best GC buffet items anywhere, especially the vegetable and dessert bars. We always eat here when in Orlando and usually more than once!
