Hi Penni!
Thank you for visiting the Moms Panel!
The answer is yes, you can visit the shop at
T-REX, at Downtown Disney, without dining there. It gives you a chance to see the restaurant even without a dining reservation.
If you decide that you would like to make a reservation, you can do so
online, or by calling (407) 939 3463, up to 180 days ahead of time.
If you have any other questions, please come back and ask me - I would be happy to help you plan your magical vacation!
