Someone on another posted said they had ADRs for T-Rex. I didn't think you needed ADRs for that restaurant, and in fact, the DIS website says they're not accepted. Do you need reservations? Do they even take them?
I made mine today -- "Priority Seating" not ADR. Call 407-828-8739. Have read that it helps to have the PS, but they also have a walk-up line that can take quite a while of waiting.
I made a reservation there in February. You have to call the actual restaurant, they can't do it through WDW-DINE. When I called, they didn't tell me it was priority seating rather than an actual reservation, and I don't know what the difference is? You can call, though, and let 'em know you're coming!
We just got back from Dis, we went there one night to 'walk-in' what a laugh that was!
It was soooooo busy! We did end up making a reservation the next day from our room for that evening, and it was not near as busy!
Its very loud though! Kids liked it.
Food was good, waitress was friendly, but it did take 40 minutes for our drinks to arrive, and we also did not get our meal at the same time as the rest of our group - my husband and I ordered the massive appetizer plater with ribs.
Which was not so massive, but it was very good, and great value. It was perfect for the two of us.
(watch out for the mandatory 18% tip for parties of 6 or more though...)
We had an ADR for dinner on SuperBowl Sunday, which let us go right up past all the people in waiting in line (who did NOT have ADRs). We were seated in about 5 minutes.
